Test Analog Outputs
Use the ATEST command to test the analog outputs. The ATEST
command will force the output to the given value, which can then be
measured with a calibrated multimeter.
ATEST command affects only the analog outputs and hence it does not
disable measurement functions. ATEST without parameters will exit the
test mode and let the measurement continue. It will also indicate the the
current analog output levels in normal measurement state.
ATEST [val1 val2]
where
val1 val2
= Analog channel output value (mA)
Examples:
