Description

Puts instrument in the Analog Output setup mode. The Analog Output steps from zero to full-scale in 20% increments, pausing for 4 seconds at each level. This repeats 5 times, after which the instrument returns to normal operation. This mode is useful for testing the Analog Output and the operation of any equipment measuring the Analog Output.

Data Parameters Sent

None

Response

<address>:<success_flag>#<checksum><CR>

Example

Command:

1DACSTEP<CR>

Response:

1:OK#261<CR> - Calibration Successful 1:FAIL#391<CR> - Calibration Failed

Notes

Note that the DACSTEP function takes some time to complete. When the command is sent to the monitor, it will immediately respond with the <address> and colon ‘:’ as an acknowledgement that the message was received. After the function is complete the rest of the response will be sent. No additional commands should be issued to the monitor until the function completes.
