Ex-demo, second-hand and repaired instruments

Every so often an instrument cannot be sold as new. It has stood on an exhibition stand, come back from a customer, arrived in a carton that took a knock, or been repaired and retested. It is still a Siglent instrument, it still measures to specification, and it costs less. What it is, why it is discounted and what warranty it carries are written on the listing before you buy — there are no surprises in the box.

What the labels mean

Four reasons an instrument ends up on this page. They are not interchangeable, and the listing always says which one applies.

Demo unit

Used at a trade fair, on our own bench or lent to a customer for evaluation. Typically indistinguishable from new and supplied in its original carton with the standard accessories.

Usually as new

Second hand

Previously owned — bought back from a customer or taken in against a new instrument. In full working order; any cosmetic wear is described and the accessories are listed individually rather than assumed.

Working, may show use

Packing or transport damage

The carton took a knock on its way to us. The instrument itself is unused and fully tested — what is marked is the box, or a cosmetic part that does not affect measurement.

Electrically new

Repaired

A fault was found and put right, by us or by Siglent, and the unit was retested afterwards. The listing says what was wrong and what was replaced. Nothing is sold with a known outstanding defect unless the listing states it in as many words.

Tested after repair

SSG5083A — 9 kHz – 13.6 GHz microwave signal generator

Ex-demonstration unit, in new condition. A 13.6 GHz microwave source is not an instrument that turns up second-hand often, and this one has never left our hands: it was used for demonstration, kept in its original packing and has the same 10 MHz OCXO reference, the same touchscreen and the same specification as a new one. There is one.

Siglent’s photograph of the SSG5000A series — the front panel in it is silkscreened with the 20 GHz model. The unit on offer is the SSG5083A, 9 kHz to 13.6 GHz. Ask us and we will send photographs of the actual instrument before you order.
  • 0.001 Hz frequency resolution across the whole 9 kHz to 13.6 GHz range
  • Phase noise better than −120 dBc/Hz at 1 GHz, 20 kHz offset (typ.)
  • AM, FM and PM analogue modulation built in as standard
  • 10 MHz OCXO reference fitted — not an option on this instrument
  • 5-inch capacitive touchscreen, LAN and USB with browser remote control
  • Two-year warranty, against three on a new one

There is exactly one of each item below. Prices are ex VAT, and the condition, contents and warranty term are on the individual listing.

Nothing here that suits you?

This page is empty as often as it is full — that is the nature of it. Tell us which instrument you are after and roughly what you want to spend, and we will let you know when one comes back. We usually know what is on its way before it is listed.

Tell us what you need

What you keep — and what is different

Buying from this page costs you less and costs you something. Both halves are worth reading.

What you keep

  • The same instrument. These are current-generation Siglent products, not obsolete stock — the model on offer is usually still in our catalogue at full price.
  • Firmware and software. The same downloads, licences and updates as a new unit. Downloads
  • Calibration. We can supply a fresh ISO or DKD/DAkkS certificate with the instrument — worth asking for on a used unit. Calibration service
  • Support. The same engineers, the same spare parts channel and the same repair route as any other instrument bought from us.
  • A proper invoice. Prices are ex VAT; EU businesses with a valid VAT number are invoiced under the reverse-charge rule, exactly as on the rest of the shop.

What is different

  • One of each. There is no reordering — when a unit is gone, it is gone, and the next one will be a different model at a different price.
  • The warranty is usually a year shorter — typically two years against the three a new instrument carries. The term is set per unit and printed in the listing, so read it rather than assume it.
  • You are buying the described condition. Any mark, missing accessory or repair history is stated up front and forms part of the sale.
  • Your statutory rights are untouched. Consumers keep the 14-day right of withdrawal under EU distance-selling rules, on exactly the terms set out in our customer information.
  • Accessories are listed, not assumed. If a probe or a lead is missing, the listing says so — and we will quote you for a new one.

What the discount actually looks like

Everything that has been through this page, at the price it was listed for — including the two that have already gone. A working current-generation instrument with a stated warranty saves you somewhere between a sixth and a fifth of the new price, whether it costs €269 or €12,999. A unit with something genuinely wrong with it saves you considerably more, and the listing explains why.

How buying one works

The same as any other order on this shop, with one extra step at the start that is worth taking.

Step 1

Read the listing

Each one names the model, the reason it is discounted, the condition, what is in the box and the warranty term. If something is not mentioned, ask before you order — not after.

Step 2

Ask us anything

Serial number, hours on the display, firmware revision, whether a specific option is licensed, photographs of a particular corner. We would rather answer first than take a return later.

Step 3

Order it like anything else

Same checkout, same payment methods, same VAT treatment. There is exactly one of each, so the listing sells out the moment someone completes the order.

Step 4

It ships from the Netherlands

Packed by us in Helmond, usually the same day for orders placed before 15:00 CET. Free EU shipping over €200.

What happens before a unit is listed

A discount is only worth having if you can trust the description. Every instrument on this page goes through the same routine first.

Powered up and self-tested

Run through the manufacturer’s own self-test routine before anything else happens.

Every input and output exercised

Channels, generator and supply outputs, trigger, interfaces and the display — checked, not assumed to work because the unit switches on.

Firmware brought up to date

Updated to the current release, so the instrument behaves like a new one out of the box.

Accessories counted

Against the standard shipping list. Missing items are replaced with new ones or named in the listing — never quietly left out.

Photographed as it is

If a mark is visible on the instrument, it is visible in the listing.

Calibrated on request

An ISO or DKD/DAkkS certificate can be issued with the unit before it ships.

Selling your instrument, or trading up

If you bought an instrument from us and no longer need it — or you need the next model up and would rather not have the old one sitting in a cupboard — we will make you an offer for it. Some of what appears on this page arrives exactly that way.

Say whether you would prefer an outright purchase or credit against a new instrument, and we will come back with a figure.

Email info@siglent.eu
Include these and we can quote straight away
  • Model and serial number
  • Roughly when and where you bought it
  • Which options or licences are activated on it
  • What is included — probes, leads, carton, manuals
  • Its condition, honestly, and a few photographs
  • Whether you want cash or credit against a new unit

Questions we are asked

What does “demo unit” actually mean?

That we owned it and it was used for demonstration rather than sold as new — on an exhibition stand, on our own bench, or lent to a customer who was evaluating it. It is not a return, not a repair and not an old model. Most demo units arrive in their original carton with the accessories unopened.

Is there a warranty?

Yes, and each listing states its own term. Both units currently on offer carry two years, against the three years a new instrument gets from us. That one year is, in practice, the only thing you give up — but the term belongs to the individual unit, so read the listing rather than assume it.

Can I change my mind after it arrives?

Consumers keep the statutory 14-day right of withdrawal under EU distance-selling rules, on the same terms as anything else in the shop. What you cannot do is return a unit because of a defect that the listing described and you accepted when you ordered.

Why is the discount 15–20% and not 50%?

Because these are current instruments in working order, not clearance of obsolete stock. A demo oscilloscope that measures exactly as well as a new one, with the same firmware and a stated warranty, is worth close to a new one. If a unit genuinely has something wrong with it, the discount is larger and the listing says why.

Do I get the probes and accessories?

Whatever the listing names, and nothing is left to inference. Where an accessory is missing we either replace it with a new one or say plainly that it is not included, and we will quote you for it separately.

Can I have a calibration certificate with it?

Yes. We can supply an ISO or an accredited DKD/DAkkS certificate with the instrument before it ships — arguably more worth having on a used unit than on a new one. Ask when you order.

Are the prices ex VAT?

Yes, like the rest of the shop. VAT is added at checkout according to the destination, and EU businesses entering a valid VAT number are invoiced under the reverse-charge rule.

There is nothing in stock at the moment — now what?

Email us and say which instrument you are after and roughly what you want to spend. Stock here is unpredictable by nature, but we know what is coming back before it is listed, and a note on file is the only way to hear about it first.

Can I sell you my Siglent, or trade it against a new one?

If you bought it from us, yes — tell us the model, the serial number, roughly when you bought it, what is included and what condition it is in. Say whether you would prefer an outright purchase or credit against a new instrument and we will come back with a figure.

Ask before you order

Serial number, firmware revision, a photograph of a particular corner, whether a licence is activated, or whether we can add a calibration certificate before it ships — ask, and you will get a straight answer. JRSE B.V. is the official Siglent distributor for the European Union.
