BCH + TCH Test Function Behavior
• The test set generates BCH + TCH on the downlink path. The BCH + TCH burst modulation is the same as
when the operating mode is set to active cell.
• Cell power is set using the
• Manually synchronizing the mobile station to the BCCH is not under direct control of the test set, it is the
user's responsibility.
• Changes to the TCH timeslot and TCH ARFCN will reconfigure the downlink (although no channel
assignment signaling will take place).
• By default, the test set's receiver is configured to receive the mobile station's signal at the TCH uplink
frequency. The test set's receiver frequency can be set manually, which decouples the automatic setting.
• Changes to the MS TX level will couple to the expected power, and the MS TX Level parameter will be
transmitted on the downlink BCCH and SACCH.
• Changes to TCH timing advance will also appear on the downlink SACCH. Whether the mobile station
makes use of these parameters is a function of the mobile station.
• All measurements are available to the user, the same as if operating mode was active mode.
Example 10. BCH + TCH Test Function Using Auto Receiver Control
The following example shows how to set up a test mode measurement using the test function BCH + TCH. In
this example the test set is configured to transmit a BCH on PGSM channel 21, a TCH on PGSM channel 31,
and receive the mobile station on PGSM channel 31 at power level 12.
1. Select test mode.
OUTPUT 714;"CALL:OPERATING:MODE TEST"
2. Select PGSM as the broadcast band (traffic channel band will automatically be set to this band).
OUTPUT 714;"CALL:CELL:BAND PGSM"
3. Select BCH as the test function.
OUTPUT 714;"CALL:FUNCTION:DOWNLINK BCHTCH"
4. Configure the receiver control to auto.
OUTPUT 714;"RFANALYZER:CONTROL:AUTO ON"
5. Set the BCH to channel 21.
OUTPUT 714;"CALL:BCH:PGSM 21"
6. Set the TCH to channel 31.
OUTPUT 714;"CALL:TCH:PGSM 31"
7. Set the MS TX Level to 12.
OUTPUT 714;"CALL:MS:TXLEVEL 12"
8. To make the measurement, set the mobile station to transmit on PGSM channel 31 at a power level of 12.
