JunTek PSG9080 Programmable Signal Generator (80 MHz - 300 MSa/s - 14-bit)

<< < (20/31) > >>

Neper:
My 9080 is too big to put it where I need it. All because of those stupid ears. I've had a closer look and they appear to be glued to the rest. Has anyone succeded in removing them without breaking everything?

Some questions for those that have bought one:

1. I read that one channel cannot modulate while the other is sweeping. Can one channel generate a basic waveform while the other channel is sweeping?

2. Is there a marker function?

3. The on-line manual shows trigger input and output bnc connectors on the rear, but from what I read here they don't appear to actually be present and the teardown video shows unpopulated points on the circuit board in that location. Are there different versions available? Did anyone get one with trigger I/O ports on the rear? (The JoyIt version also shows these rear panel connectors on the website images).

Yes, the second channel just keeps the last wave settings in Sweep mode.

No.

The rear BNC are used to connect with other PSG9080, one connector for previous PSG9080 and the second connector for the next PSG9080 in a sequence. It uses some internal and strange pulse structure, so you will be unable to use it as a trigger or a sync for the sweep.

some pictures from my tests taken with 14-bit ADC running at 96 MHz:

1) spectrum sine wave 3 MHz 4.1 Vpp (actual 2.05 Vpp at 50 Ω input)
2) spectrum square wave 3 MHz 4.1 Vpp (actual 2.05 Vpp at 50 Ω input)
3) oscillogram square wave 50 kHz
4) oscillogram ramp wave 10 kHz
5) oscillogram triangle wave 20 kHz
