As shown in the examples above, the dBm data is output in fixed rotation,
while the WATT data is output in scientific notation. The exponent may be
converted as follows:
1.000W = 1.000E–0 1.000 mW = 1.000E–6
1.000 mW = 1.000E–3 100.0 nW = 100.0E–9
100.0 mW = 100.0E–6 10.00 nW = 10.00E–9
10.00 mW = 10.00E–6 0.100 nW = 0.100E–9
For dB (rel), including % and VSWR data, the display data is output in
fixed notation just as dBm data is.
REF Set the reference value.
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.
RNG Sensor measurement range hold.
Syntax:
RNG<number>
<number>:
1 = Range 1 (ML2430A range 5)
2 = Range 2 (ML2430A range 4)
3 = Range 3 (ML2430A range 3)
4 = Range 4 (ML2430A range 2)
5 = Range 5 (ML2430A 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 ML2430A range 5, and ML4803 range 5 (the highest power range) is
equivalent to the ML2430A range 1. Refer to page 4-6 for more information
on sensor ranges.
SRQ Turns on or off the SRQ on output data ready.
Syntax:
SRQ<state>
state:
0 = OFF
1 = ON
