protocols, and pattern memory. Two 10 MHz frequency counter and programmable clock output to 20 MHz
34951A
4-channel isolated D/A
converter with waveform
memory
Output DC voltage up to ± 16 V or DC current up to ± 20 mA.
Output waveforms with a 200 kHz update rate and 16 bits of resolution.
Use on-board memory to create point-to-point waveforms with more than 500,000 points.
34952A
Multifunction module with 32-
bit DIO, 2-ch D/A, and
totalizer
Four 8-bit digital I/O channels, two ± 12-V analog outputs, and a 100 kHz gated totalizer.
34959A
Breadboard component
module
Create your own custom designs with access to the +12 V and +5 V supplies, 16 GPIO ports, 4 Analog Bus
drivelines, and 28 relay drivelines.
Alternatively, you may use the 4 Analog Bus drivelines as 4 additional general-purpose relay drivelines.
Refer to Internal DMM / Analog Bus ratings.
