Description
Clock and timing circuits judge a generator by its edges, so a clean sine wave matters less. The Keysight 33621A waveform generator makes pulses up to 100 MHz with less than 1 ps of jitter. It does so from a single 120 MHz channel, and Lost in HCM lists it for rental and sale.
Why clean edges matter in timing tests
Because a slow or jittery edge can hide the very fault you are hunting, source quality matters. Low jitter therefore helps you separate a circuit problem from a source problem. Trueform architecture also produces arbitrary waveforms without the point-skipping behavior of conventional DDS generators, so complex shapes keep their detail. Clock, strobe and pulse validation all benefit as a result.

Sample rate, memory and control on the Keysight 33621A waveform generator
One GSa/s sampling and 14-bit resolution keep fine waveform detail and small amplitude steps. Standard memory holds 4 MSa, and a 64 MSa option suits longer sequences. Front-panel editing, BenchVue control and waveform import cover both interactive and automated work. Still, name each option in your request, because the base unit does not include them all.
Where it gets used
- Sensor, filter and amplifier stimulus.
- Clock, pulse and timing-circuit validation.
- Embedded, automotive and education laboratories.
- Arbitrary-waveform and modulation research.
If your test needs two related signals, a two-channel model suits it better. For a single stimulus with sharp edges, however, this one channel is enough.
Ordering through Lost in HCM
Teams often rent a Keysight 33621A waveform generator for one validation push and buy only if the work repeats. Either path begins when you request a quote from Lost in HCM. Mention the memory option, cables, software functions and the date you need delivery. Rental also suits R&D peaks and short audits, when you need extra capacity for weeks rather than years. More choices sit in the waveform and function generators category, and the Keysight website carries official documents. Questions? contact SMK Vietnam.
33621A questions answered
Does it have a second output?
No. It has one channel, so pick a two-channel model when your test needs paired signals.
Can I add longer waveform memory?
Yes. Standard memory is 4 MSa and 64 MSa is optional, so name the option in your request.
Which interfaces does it list?
USB and LAN, plus optional GPIB for racks that need it.
