Test Parameters
Parameter descriptions
16 RT External Pad and Cable Loss
This parameter adjusts measurement results and RF Generator
operation to cancel out any loss due to external cables or attenuators
connected to the HP/Agilent 8922 RF IN\OUT connector. After you
enter the loss in the value field, all measurements will be adjusted in
order to take into account the offset level.
Note that the value of parameter 16 appears on any hardcopy printout
at the start of each test and after a Dual-Band handover.
Default value Not applicable. Note that if the value of parameter 16 is set to 0, then
the RF Offset value of the HP/Agilent 8922 is taken and used during
the execution of a procedure. This does not apply if you started the
procedure for Dual-Band, as different offsets are needed for each
frequency band. In this case, the offset is always taken from the value
of parameter 16.
Example If a 30 dB attenuator is connected in line with the mobile station’s
antenna, you would enter 30 in the value column. Next, if you wanted a
−90 dBm input to the mobile station, you would leave the RX RF level
for signaling (parameter RX RF level for signaling) at its
default value of
−90 dBm.
17 RT Nominal Supply Voltage
This parameter sets the nominal dc power-supply voltage when a power
supply is under GPIB control. See “Setting up a GPIB Power Supply” on
page 37 for details.
Default value The default power supply voltage is 0 V.
Example If your mobile specification requires a nominal supply voltage of +13
Vdc, you would enter 13 in the value column.
Use a power supply that supports SCPI programming mnemonics. For a
list of supported power supplies, see “Power supplies” on page 37.
