Service request programming example
The example below shows how to program the 2601B-PULSE to generate a service request (SRQ)
when the current limit is exceeded.
-- Clear all registers.
status.reset()
-- Enable the current limit bit in the current limit register.
status.measurement.current_limit.enable = status.measurement.current_limit.SMUA
-- Enable the status measure current limit bit.
status.measurement.enable = status.measurement.ILMT
-- Enable the status SRQ MSB.
status.request_enable = status.MSB
Polling for SRQs
To determine if the 2601B-PULSE is the GPIB device that generated the service request (SRQ),
serial poll the instrument for the status byte, and test to see if the corresponding summary bits
are set.
How do I store measurements in nonvolatile memory?
After the measurements are complete, you can save the reading buffer data to the nonvolatile
memory in the instrument.
To save the reading buffer data:
1. From the front panel, press the STORE key, and then select SAVE.
2. Select INTERNAL to save to internal nonvolatile memory.
3. Select one of the following:
â–ª SMUA_BUFFER1
â–ª SMUA_BUFFER2
4. The front panel displays Saving... This may take awhile.
5. Press the EXIT (LOCAL) key to return to the main menu.
For additional information, see Saving reading buffers (on page 5-4).
