I want to hard reset the BB60C without unplugging it from USB port.
According to the Spike SCPI programming manual,
PRESet, Presets the active device. This will power cycled the active device and return the software to the initial power on state. This process can take between 6-20 seconds depending on the device type.
PRESet?, Presets the active device. This will close and reopen the active device.
This process can take between 6-20 seconds depending on the device type. Returns 0 or 1 depending on success.
I tried both PRESet and PRESet?. But both seemed to behave in the same way that the READY/BUSY green LED turned off for about a half second and then turned on again into flashing red(orange?) light.
This is strange for that
1. Both PRESet and PRESet? should be back to stable green light state at the reset end.
2. PRESet? should NOT lead to LED off whatsoever otherwise it may confuse the user that the power has be cycled.
3. PRESet? returned value of ‘1’. Does it represent success or failure? There is no explicit interpretation in the manual.
Could you help explain the reasoning behind this?
Thanks a lot.

SYST:PRES? will return 1 on success. It will power cycle the device, which will result in the LED turning off for a brief period. For most of our devices solid green indicates on and ready (but not active), while when actively making measurements you will see orange/red. Since preset will power cycle the device and return to power up conditions in the software, the device will be actively sweeping after preset and you will see red/orange LED.
I hope this helps.

Thanks for the reply.
Does it mean that essentially SYST:PRES and SYST:PRES? affect the BB60C in the same way?
If so, the only difference between the two commands would be with or without returned value.
Please correct me if I’m wrong.

You are correct in your assumption.
