Cw Operating Mode; Cw Test Mode Operation - Agilent Technologies 8960 Series Reference Manual

CW Operating Mode

CW operating mode provides an unmodulated carrier of adjustable frequency and amplitude, manual
adjustment of the measurement receiver and demodulation (uplink) receiver frequencies, and manual setting
of the expected CW input power.
NOTE Manual receiver control settings made while using the CW operating mode can affect manual
receiver settings made in other operating modes (such as FDD Test mode). When changing
operating modes and using manual receiver settings, always verify that the manual receiver
settings are correct for the new operating mode.

CW Test Mode Operation

When the test set's operating mode is set to CW:
• No over the air signaling is used. Therefore there is no synchronization between the mobile station (UE)
and the test set.
• No demodulation or channel decoding is available.
• An unmodulated RF signal can be generated while analyzing another signal (at the same frequency or at a
different frequency). No interaction exists between these controls.
• With the exception of mobile reported values (which are only available in Active Cell mode), all test set
measurements are accessible. However, measurements requiring protocol triggering, such as waveform
quality, cannot be made. Immediate triggering should be used for most measurements because no overhead
signaling is occurring. Protocol triggering will time-out (if time-outs are enabled) or report an integrity
indicator other than zero (0) and not provide valid results. RF Rise triggering is meant for bursted signals,
such as a PRACH burst, and may or may not work with other signals.
• Expected CW power, measurement receiver frequency, and uplink receiver frequency are available as
manual settings only; no automatic control is provided.
CW Mode Operation
The following command examples show you how to control each function for CW operating mode:
1. Select CW operating mode:
OUTPUT 714;"CALL:OPERating:MODE CW"
2. Set the cell power output level to be transmitted by the test set:
OUTPUT 714;"CALL:POWer -45 DBM"
3. Set the RF generator frequency:
OUTPUT 714;"CALL:RFGenerator:FREQuency 870 MHZ"
4. Set the expected CW power level to be received by the test set:
OUTPUT 714;"RFANalyzer:CW:EXPected:POWer 23 DBM"
5. Set the measurement receiver frequency:
OUTPUT 714;"RFANalyzer:MANual:MEASurement 870.030 MHZ"
