CALL CONTROL
RX/TX Cntl
This function controls automatic screen changes between the RX TEST and TX
TEST screens during radio testing. It is divided into two fields:
The
Auto/Manual field enables/disables automatic switching between the RX
TEST and TX TEST screens under certain testing conditions.
• Auto allows automatic screen changes between the RX TEST and TX TEST screens
while testing radios.
• Manual requires you to select the RX TEST or TX TEST screen when performing ra-
dio tests.
The Carrier/PTT field specifies the condition that will cause automatic screen
changes.
• Carrier causes the instrument to automatically switch from the RX TEST screen to
the TX TEST screen when an RF carrier is detected. The screen returns to RX TEST
when the carrier is no longer detected.
• PTT (Push-To-Talk) causes the instrument to automatically switch from the TX TEST
screen to the RX TEST screen when a microphone connected to the MIC/ACC connec-
tor is keyed. The screen changes back to TX TEST when the microphone is no longer
keyed.
Operating Considerations
CAUTION: The Test Set can be damaged by connecting a reverse-power signal to the DUPLEX OUT port
of >200 mW.
If Auto and Carrier are used together, the screen may continuously change
between RX TEST and TX TEST. This only occurs if the RF IN/OUT port is used
with the RF Generator
Amplitude set ≥ 35 dBm (a much higher level than is
typically used for receiver tests). To prevent this problem, set the
Amplitude
≤
35 dBm or Off, or use the DUPLEX OUT port for the RF Generator’s output.
