:OUTPutn[:CHANnel[m]]:APMode?
:OUTPutn[:CHANnel[m]]:APMode?
Queries whether the user has amended the power value or the attenuation value.
This use of this command is optional.
Included for compatibility with Agilent 8156A mainframe.
none
boolean 0 User has amended the attenuation value.
1 User has amended the power value.
→
OUTP1:APMode? 0<END>
All attenuator modules.
:OUTPutn[:CHANnel[m]]:POWer
:OUTPutn[:CHANnel[m]]:POWer<wsp><value>[PW | NW | UW | MW | W | DBM ] | MIN | MAX |
DEF
Sets the output power value (P ).
If your attenuator module does not include the power control feature, the new filter attenua-
α
tion ( ) is calculated from the reference power (P
filter (new)
P (dBm) = P (dBm) -
set(new) ref
If your attenuator module includes the power control feature, the filter attenuation is changed
until the set power (measured by the module's internal power meter) has been reached.
P (dBm) = P
set(new) att(new)
If the set power cannot be achieved ExP (indicating 'Excessive Power' ) is displayed, and the
appropriate GPIB status bit is set. The status of these bits can be queried using ":STA-
Tus:QUEStionable:CONDition[:LEVel0]?" on page 71
<value> Desired output power (if unit not specified current unit is used).
MIN | MAX | DEF Sets the output power to the module limits, or the module default.
none
OUTP1:POW 12
All attenuator modules.
:OUTPutn[:CHANnel[m]]:POWer?
:OUTPutn[:CHANnel[m]]:POWer<wsp>MIN | MAX | DEF
Without the optional parameter, queries the output power value.
MIN | MAX | DEF Queries the output power module limits, or the module default.
4 byte Intel floating point; output power in current power unit.

OUTP1:POW? 12<END>
All attenuator modules.
