The HP 3245A Universal Source is a versatile precision instrument that combines DC and AC signal generation, offering both high-resolution DC outputs and synthesized AC waveforms up to 1 MHz.
| Function | Details |
|---|---|
| DC Outputs | 24-bit resolution, 60 ppm accuracy, voltage & current modes |
| AC Outputs | Sine, square, triangle, ramp, pulse up to 1 MHz (100 kHz for ramp/pulse) |
| Arbitrary Waveforms | Custom waveform generation |
| Accuracy | 0.4% amplitude accuracy for AC |
| Integration | Programmable for automated test systems |
| Outputs | Floating, isolated for flexible connections |
The front panel outputs of the stock instrument are handled via BNC connections, which is inconvenient for interconnections and testing. Ian Scott Johnson has fitted good quality banana jacks on his 3245A, so I decided to do the same.
I salvaged some high quality tellurium-copper banana jacks from a scrapped Valhalla 2790B, and used those for the installation.
I also used shielded, stranded, silver-plated, Teflon insulated wire to connect the new jacks to the output connections on the main PCB. Gold plated ring terminals completed the job.
Now I can use either banana jacks or two-conductor shielded cable or BNC cable at the outputs.
