GPIB Command Conventions
CALL[:CELL[1]]:POWer[:SAMPlitude][:SELected]
|
Function
|
The setting form of this command performs two functions: (1) sets the Cell Power level and (2) turns the cell power on/off state to on. The query form returns the Cell Power level (including compensation for amplitude offset) or NAN.
The optional [:SELected] keyword in this command specifies that the Cell Power level being set or queried applies to the current system type. The current system type can be changed using the
CALL[:CELL]:SYSTem[:TYPE]
command.
Cell Power and AWGN (see
CALL:AWGNoise
) are absolute power levels and make up the total forward channel RF output power.
The return value for this query is not necessarily the cell power level being transmitted by the test set at the moment this command is processed by the test set. It may return a value that the test set has been requested to transmit, but that has been pended or delayed for some reason. See
Troubleshooting Setting Power Levels
for possible causes. To query the cell power level the test set is transmitting at the moment the command is sent, use the
CALL:STATus:CELL[1]:POWer:[AMPLitude][:SELected]?
command.

Range:
-
CDMA: -170 dBm/1.23 MHz to +37 dBm/1.23 MHz, 9.91 E+37
(-120 dBm/1.23MHz to -13 dBm/1.23 MHz actual hardware range with amplitude offset = 0)
The actual power range is defined by adding the value of the associated Amplitude Offset to the range shown above. See
Cell Power, AWGN Power and Total RF Power Ranges
.

CALL[:CELL[1]]:POWer:STATe[:SELected]
|
Function
|
Sets/queries the cell power state.
The return value for this query is not necessarily the cell power state at the moment this command is processed by the test set. This command may return a state that has been requested of the test set, but that has been pended or delayed for some reason. See
Troubleshooting Setting Power Levels
for possible causes. To query the cell power state of the test set at the moment, use the
CALL:STATus:CELL[1]:POWer:STATe[:SELected]?
command.
The optional [:SELected] keyword in this command specifies that this query applies to the current system type. The current system type can be changed using the
CALL[:CELL]:SYSTem[:TYPE]
command.
