That does look strange when changing the voltage range from +/-500mV to +/-200mV, it would be useful to know how high a voltage overrange there is, so changing from the +/-500mV range to +/-20V range would be interesting to see.
The OP was after 5 to 15 PicoScopes which is an unusual request. Most cases for adding multiple scopes are unique so we prefer to advise people in relation to their specific needs which is why we will often ask people to email in to support@picotech.com Can you give more detail on exactly why you ar...
There is a function in the API to set the frequency counter although there are currently no examples to show this PREF0 PREF1 PICO_STATUS PREF2 PREF3 (ps4000aSetFrequencyCounter) ( int16_t handle, PS4000A_CHANNEL channel, int16_t enabled, PS4000A_FREQUENCY_COUNTER_RANGE range, int16_t thresholdMajor...
If you look at the Scope button on the top of the display you will see Samples 125 (1290), PicoScope 7 is only collecting 125 samples, but the softare is using sin(x)/x interpolation to bump this up to 1290 which is why you are seeing the ripple. If you are using the same sampling settings as PicoSc...
The Pk to Pk voltage looks like 1.25V which is half of the signal generator voltage. The generator is probably specified to output the 5V into an open circuit, but as you are connecting to a 1MOhm input impedance scope and you have the generator set to high impedance, you have a 1MOhm + 1MOhm voltag...
The section at line 86 is wrong, as it is setting the PulseWidth when it should set the Channel, PulseWidth is set correctly in the section at line 112, # Set channel A direction as rising and level num_directions = 1 ChannelDirection = ps.PS5000A_DIRECTION( ps.PS5000A_CHANNEL["PS5000A_CHANNEL_A"], ...
The pulse width type enums can be found here https://github.com/picotech/picosdk-python-wrappers/blob/master/picosdk/PicoDeviceEnums.py For a simple pulse width trigger Channel Properties for Channel A to the voltage and hysteresis required with mode Level Channel Conditions for Channel A need to be...
