SSA5000A
Fifteen options for the SSA5083A and SSA5085A, every one a software key against an instrument you already own: nothing to fit, nothing to return. They cover what a spectrum analyser gets bought for one capability at a time: reaching 26.5 GHz, seeing weak signals, capturing in real time, and the measurement suites for pulse, phase noise, noise figure, EMI pre-compliance and modulation analysis. Below them the four pieces of hardware that go with the series, including the NSD28 driver the noise-figure option needs. Every card links to its own page with specifications, set-up and documents.
All instruments
Frequency range and sensitivity
Two of these change what the instrument physically reaches. ⚠ SSA5000-F5 turns a 13.6 GHz SSA5083A into a 26.5 GHz SSA5085A by key alone — the hardware is already there. The pre-amplifiers must match your instrument's range: P3 for 13.6 GHz, P5 for 26.5 GHz.
Turns a 13.6 GHz SSA5083A into a 26.5 GHz SSA5085A by key.
Low-noise pre-amplifier to 13.6 GHz — lowers the noise floor.
Low-noise pre-amplifier to 26.5 GHz — lowers the noise floor.
Real-time analysis, bandwidth and data output
The SSA5000A has 25 MHz of analysis bandwidth as standard; SSA5000-B40 takes it to 40 MHz. SSA5000-IQA records raw I/Q to a 1 GByte buffer for post-processing, and SSA5000-IFO brings a 120 MHz IF out on a BNC (40 MHz wide, −13 to +5 dB conversion gain) for an external receiver.
Real-time spectrum analysis — sees signals a swept sweep misses.
Widens the analysis bandwidth from 25 MHz to 40 MHz.
Records raw I/Q to a 1 GByte buffer for post-processing.
Brings the 120 MHz IF out on a BNC for an external receiver.
Measurement applications
Guided measurement suites rather than manual cursor work. ⚠ SSA5000-NF also needs the NSD28 noise source driver and a +28 V noise source with its ENR table: the SSA5000-NF page explains the Y-factor set-up step by step, the NSD28 page the driver. SSA5000-EMI adds the CISPR 16-1-1 quasi-peak and voltage-average detectors with the 200 Hz / 9 kHz / 120 kHz / 1 MHz filters and EN550xx, GB9254 and FCC Part 15 limit lines.
One-button channel power, ACPR, OBW, C/N, harmonics and TOI instead of manual marker work.
Automated pulse measurement — width, period, duty, rise and fall, overshoot.
Phase-noise measurement with log plot, decade table and spur list.
Noise-figure and gain measurement for amplifiers and converters.
CISPR 16-1-1 filter bandwidths, a quasi-peak detector and limit lines for pre-compliance EMI work.
Modulation analysis
SSA5000-AMA covers AM, FM and PM with rate and deviation accuracy figures. SSA5000-DMA covers ASK, FSK, MSK, PSK, DPSK and QAM to 256 with EVM, constellation and eye views. SSA5000-BT covers Bluetooth Low Energy, Basic Rate and Enhanced Data Rate across 2.4020 to 2.4835 GHz.
AM, FM and PM demodulation with depth, deviation, rate and SINAD on the recovered audio.
Constellation, eye, EVM and frequency error for ASK, FSK, PSK, MSK and QAM signals.
Bluetooth LE, Basic Rate and Enhanced Data Rate transmitter measurement.
Related hardware and accessories
⚠ The 10M_OCXO_L reference is listed by Siglent as factory installed. If you already own the analyser, ask us before ordering it — it may not be retrofittable. The NSD28 is required by the noise-figure option (USB-A in, switched +28 V BNC out; see its page for the whole set-up), and the 2.92 mm adaptor protects the instrument's own RF input connector, which is the expensive part to replace. Cables: the input is 2.92 mm male. The S40-29M29F-1M (2.92 mm, 40 GHz) and the SMAF-SMA-26L (SMA female to male, 26 GHz) connect directly; the SMA-SMA-26L and SMA-SMA-18L connect through the adaptor. See the RF cable selection guide for the full range.
Noise source driver — required by the noise-figure option.
High-accuracy OCXO 10 MHz reference.
H-field and E-field probes, 300 kHz – 3 GHz, for locating emission hotspots on a board.
2.92 mm (F) to (F) adaptor, DC to 40 GHz — connector saver.
Prices are per license and may exclude VAT; confirmed at checkout. Some options require a compatible firmware version or hardware (e.g. a logic probe for MSO) — see each product. Software licenses & activation keys are delivered electronically and are excluded from the 14-day EU return right once the key has been issued. Errors & omissions excepted.
