Front Panel Access to Receiver Controls

To access receiver control settings on the test set's front panel while using FDD Test operating mode, press the
key, press the key until 3 of 3 is displayed, and select Receiver Control ( ). See Figure

Expected Power

To make accurate measurements, the test set needs to know how much power to expect at its RF IN/OUT port;
this is referred to as the Expected Power. If a measurement uses autoranging (such as the thermal power and
ACLR measurements), the expected power level is calibrated by the test set before making the measurement
and does not need to be set by the user. For measurements that do not use autoranging, it gets the expected
power value from the MS Target Power setting during automatic receiver control, or by the user specifying the
Manual Power value with the receiver Power Control set to Manual. Refer to Figure 11. "Selecting Auto or
Manual Receiver Control".
The test set uses the expected power level to establish a range of acceptable input levels into its receivers. If
the received signal is above or below the acceptable range, an Over Range or an Under Range message is
displayed and the integrity value for the measurement is set to 5 or 6 (respectively).
You can enter an expected power level setting that is beyond the actual capability of the test set's hardware.
This is because expected power is intended to reflect the potential range of RF power at the mobile station
(UE). This range of RF power is meant to accommodate the use of a gain or loss network between the mobile
station and the test set. See "Amplitude Offset" on page 47 for details about entering amplitude offsets.
The upper and lower limits of expected power provide boundaries for the combination of amplitude offset and
expected power. If you set expected power to +52 dBm and the amplitude offset to − 3 dB, the calculated
receiver power will be +49 dBm, but the test set shall be set to +43 dBm, the upper limit of the hardware.

GPIB Equivalent Commands for Receiver Control

The following settings control the test set's receivers:
Power Control (Except for CW Mode)
The expected power from the mobile station (UE) is set manually by enabling manual power control using
the"RFANalyzer:CONTrol:POWer:AUTO" command, and by using the
"RFANalyzer:MANual:POWer[:SELected]" command to set the level.
CW receiver power
When using the CW operating mode, the expected power from the mobile station is set manually using the
"RFANalyzer:CW:EXPected:POWer" command.
