SDS5000L-PA — Power analysis
Switching loss, SOA, ripple, PSRR, inrush and efficiency — power measurement as a guided application.
Supplied as a licence key issued against the instrument's serial number. There is no hardware to fit and nothing to return: the code is entered in the instrument's own menu and the function is available immediately, on the instrument you already own.
What this option does
What it does
Adds the power-analysis application. From a voltage channel and a current channel it measures power quality, current harmonics, inrush current, switching loss, slew rate, modulation, output ripple, turn-on and turn-off, transient response, PSRR, efficiency and safe operating area, with results tabulated rather than left to cursors.
What you use it for
Repeatable switching-converter measurements to a defined method, on a 1U instrument whose 12-bit resolution keeps small signals readable next to large ones — controlled over LAN from the rack or the bench.
In practice
Qualifying a 48 V to 12 V converter across its load range: turn-on and turn-off loss per cycle, output ripple and PSRR, then efficiency at each load point — repeated identically on the next unit.
You need a high-voltage differential probe and a current probe. Their different propagation delays must be removed first — that is what the DF2001A deskew fixture is for.
What it measures
From the SDS5000X HD / SDS5000L data sheet EN01A.
| Measurements | Power quality, current harmonics, inrush current, switching loss, slew rate, modulation, output ripple, turn-on / turn-off, transient response, PSRR, efficiency, SOA |
| Inputs | A voltage channel and a current channel per measurement; eight channels allow four pairs |
| You also need | A high-voltage differential probe, a current probe and the DF2001A deskew fixture |

Questions about SDS5000L-PA
What else do I need besides the licence?
A high-voltage differential probe for the voltage, a current probe for the current, and the DF2001A fixture to remove the delay between the two probes before you measure switching loss.
Is the harmonics result a compliance test?
It is a pre-compliance measurement: a reliable indication of where a design stands before it goes to an accredited test house, not a certificate.
Does it work on every SDS5000L?
Yes — the 350 MHz, 500 MHz and 1 GHz models. With eight channels you can measure up to four voltage and current pairs at the same time.
How is the licence delivered?
Supplied as a licence key issued against the instrument's serial number. There is no hardware to fit and nothing to return: the code is entered in the instrument's own menu and the function is available immediately, on the instrument you already own. Add the instrument’s serial number to your order, or send it to us afterwards — the key is issued against it.
Can I return a licence?
Software licences and activation keys are delivered electronically and are excluded from the 14-day EU return right once the key has been issued. If you are unsure which key you need, ask us first — with your serial number we can confirm it.
Not sure this is the right key?
Send us your serial number and what you want to measure. We will confirm the exact option before you order.
