ITEST
Use the serial line to test the operation of the analog outputs. Use the
command ITEST [aa.aaa bb.bbb] to force the analog outputs to
entered values. The set values remain valid until you issue the
command ITEST without parameters or reset the transmitter.
Syntax: ITEST [aa.aaa bb.bbb]
where
aa.aaa = Current or voltage value to be set for channel 1 (mA or V)
bb.bbb = Current or voltage value to be set for channel 2 (mA or V)
Example:
>itest 20
Ch1 (Tdf ) : * 20.000 mA H'CCD3
Ch2 (x ) : * 20.000 mA H'CCCB
>itest 20 5
Ch1 (Tdf ) : * 20.000 mA H'CCD3
Ch2 (x ) : * 5.000 mA H'34BD
