GPIB Operation ML4803A Emulation Commands
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 8-95
REF (Set the reference value)
RNG (Sensor measurement range hold)
SRQ (Turns on or off the SRQ on output data ready)
STA (Restart averaging reading)
WAT (Sets the display channel units to Watts)
Syntax: REF<value>
value: Reference value
Remarks: If the display channel is already in relative mode the display value will
be updated to be relative to the new reference value set. When the
display channel is put into relative mode the reference value will be over
written with the correct relative value to make the display read 0 dB.
Syntax: RNG<number>
<number>:
1 = Range 1 (ML243xA range 5)
2 = Range 2 (ML243xA range 4)
3 = Range 3 (ML243xA range 3)
4 = Range 4 (ML243xA range 2)
5 = Range 5 (ML243xA range 1)
A = Auto ranging
Remarks: When the ML2430 is being used to emulate the ML4803, the ranges are
reversed; that is, ML4803 range 1 (the lowest power range) is equivalent
to the ML243xA range 5, and ML4803 range 5 (the highest power range)
is equivalent to the ML243xA range 1.
Syntax: SRQ<state>
state: 0 = OFF
1 = ON
Remarks: When SRQ0 is issued, the SRQ will no long turn off and on with each
reading. The SRQ is set back on by the SRQ1 command or by requesting
data.
Syntax: STA
Syntax: WAT
Remarks: Turns off relative mode. Relative is not available in this mode.
