Description
A converter test is only as honest as the stimulus behind it. The Keysight M8190A waveform generator is a 1- or 2-channel AXIe module that draws that stimulus at up to 12 GSa/s. Lost in HCM lists it for rental and sale, with service on request.
Speed or resolution: two DAC modes
The module runs at 12 GSa/s with 12 bit, or at 8 GSa/s with 14 bit. So you choose the mode that fits the job. Wideband signals favor the faster mode, while precise amplitude work favors the extra bits. Analog bandwidth reaches up to 5 GHz, although installed options shape the final figures.
| Maximum sample rate | 12 GSa/s at 12 bit |
|---|---|
| High-resolution mode | 8 GSa/s at 14 bit |
| Analog bandwidth | Up to 5 GHz |
| Channels | 1 or 2, hardware option |
| Memory | 128 MSa, or up to 2 GSa per channel with the option |
| Form factor | 1-slot AXIe module |
Clean signals for converters and jitter margins
Typical SFDR reaches up to 90 dBc, and intrinsic jitter is 15 fs rms. Those figures matter when you probe an ADC or test a receiver’s jitter margin. Advanced sequencing and the optional long waveform memory also keep extended scenarios running. In addition, both Keysight and third-party waveform software can drive the module.
Where the Keysight M8190A waveform generator earns its slot
- Radar and electronic-warfare scenario generation.
- ADC and jitter-margin testing in converter labs.
- High-speed serial and multilevel stimulus.
- Wideband communications and OFDM waveform playback.
Teams often weigh it against the Tektronix AWG70000 and Rohde & Schwarz SMW or AFQ-class solutions. Compare sample rate, resolution, bandwidth, memory, channel sync, chassis needs and software on your own test plan.
Plan the chassis before the module
An AXIe module cannot run alone, so it needs a compatible chassis and controller. Therefore, ask about both when you request a quote. Then confirm channel count, DAC modes, memory, amplifier, digital upconversion, sequencer and clocking for the unit on offer.
Rent for a campaign or buy for the lab
A fixed validation campaign suits a rental of the Keysight M8190A waveform generator. For example, a radar prototype may need wideband stimulus for only a few weeks. A converter lab with daily work may prefer to own one. Please request a quote from Lost in HCM with your channel count, memory, dates and delivery site. Browse the wider waveform and function generators range, or contact SMK Vietnam if you want help with the options. The Keysight website holds the official data.
M8190A questions
Can I run it without a chassis?
No. It is an AXIe module, so it needs a compatible chassis and controller.
How many channels will I get?
Hardware options offer one or two channels, so state which one you need.
Which mode suits wideband signals?
The 12 GSa/s mode at 12 bit gives the highest sample rate. The 14-bit mode runs at 8 GSa/s and adds vertical resolution.
