CHAN NEL
Syn tax: CHRES <c>,<val>
c: 1 or 2
val: 1 to 3
Re marks: Set the num ber of dec i mal places dis played for the spec i fied chan nel. For
ex am ple, spec i fy ing CHRES 1, 1 would yield a dis play of 1.5 dBm;
CHRES 1, 2 would yield 1.47 dBm; CHRES 1, 3 would yield 1.468 dBm.
If the num ber to be dis played is too large for the num ber of dec i mal
places se lected, the dec i mal places dis played will be re duced so that the

Re marks: DBM 0dB is equal to 1mW read out mode
W = Watts read out mode
V = Volts read out mode. This se lec tion is au to mat i cally made when the
chan nel in put con fig u ra tion is set to Ex ter nal volts (EXT V).
DBUV = dB
mV, 0dB is equal to 1 mV in read out mode.
