I bought a pico scope 2205 mso a few days ago and it seems that the advanced triggers don't work, actually no trigger seems to work other than the simple edge. I tried several settings, both channel A and B, nothing seems to work. I am not new to oscilloscopes, but never used a PC based one before, so maybe I am doing something wrong.
So here is my setup:
- The test signal is generated by the AWG of the scope, it is set to arbitrary waveform in bit-stream mode it generates the following sequence 111001010000 ( so we have a wide pulse at the beginning and some smaller pulses, what I'd like is to trigger only on the wide pulse (f=1Khz,A=1V,offs= 0V), the first wide pulse has +width of ~130us, the small ones ~40us)
- Channel A, auto-range, DC, the AWG output is probed
- 100us/div, 33.33MS/s
-Trigger setup: Source:A, pulse direction:+, condition: greater than, threshold 800mV, hyst:3%, time 100uS
- trigger mode repeat
EDIT: - trigger type: pulse width
Expected result: scope triggers on the wide pulse
Actual result: no trigger, it fails to trigger if the time parameter !=0s
Here is my scope data:
PicoScope® 6 - PC Oscilloscope software version: 188.8.131.52 (windows 7, 64bit intel 2600k)
Model: PicoScope 2205 MSO
Calibration Date: Monday, February 27, 2012
Hardware Version: 1
Driver Version: 184.108.40.206
Firmware Version: 220.127.116.11 / 0.2.2.0
Am I doing something wrong?
Can AWG and advanced trigger be used at the same time?
Is this a known bug? Can it be fixed with a new firmware? Is my scope defective?
Please help, I am very frustrated that this doesn't work, it should be pretty basic stuff.
