STATUS (Status Message)
Syntax: STATUS
Remarks: Replies with the power meter’s current state code. In this format, the
number of letters specifies the number of digits, with preceding zeroes
for padding. The format is:
’ABCDEFGHIJKLMNNOOPQRRRRSSSSTUVWXYZ12’
where:
A = Operating mode: '0' = Digital readout, '1' = Profile mode channel 1,
'2' = Profile mode channel 2, '3' = Power vs. Time channel 1, '4' = Power
vs. Time channel 2, ‘5’ = Source sweep chan. 1, ‘6’ = Source sweep chan.
2.
B = Channel 1 input configuration: '0' = OFF, '1' = A, '2' = B, '3' = A–B, '4'
= B–A, '5' = A/B, '6' = B/A, '7' = EXT Volts.
C = Channel 2 input configuration: '0' = OFF, '1' = A, '2' = B, '3' = A–B, '4'
= B–A, '5' = A/B, '6' = B/A, '7' = EXT Volts.
D = Channel 1 units: '0' = dBm, '1' = Watts, '2' = Volts, '3' = dBmV, '4' =
dBmV.
E = Channel 2 units: '0' = dBm, '1' = Watts, '2' = Volts, '3' = dBmV, '4' =
dBmV.
F = Channel 1 relative status: '0' = Rel OFF, '1' = Rel ON.
G = Channel 2 relative status: '0' = Rel OFF, '1' = Rel ON.
H = Channel 1 low limit state: '0' = OFF, '1' = ON.
I = Channel 1 high limit state: '0' = OFF, '1' = ON.
J = Channel 2 low limit state: '0' = OFF, '1' = ON.
K = Channel 2 high limit state: '0' = OFF, '1' = ON.
L = Sensor A measurement mode: '0' = Default, '1' = MOD average, '2' =
Custom.
M = Sensor B measurement mode: '0' = Default, '1' = MOD average, '2' =
Custom.
NN = Sensor A range hold: Manual = '01' to '05', AUTO = '11' to '15'.
OO = Sensor B range hold: Manual = '01' to '05', AUTO = '11' to '15'.
P = Sensor A averaging mode: ‘0’ = OFF, ‘1’ = AUTO, ‘2’ = Moving, ‘3’ =
Repeat.
Q = Sensor B averaging mode: ‘0’ = OFF, ‘1’ = AUTO, ‘2’ = Moving, ‘3’ =
Repeat.
RRRR = Sensor A average number. For Profile and Source Sweep
modes, this number is between 1 and 512. For digital Readout or Power
vs. Time modes, the values are either 1 to 512 or, if in AUTO averaging
mode, 513 to 1024.
