2. Set the parameters as shown in the table below.
2.4.2 Setting the Output Stage
The term "output stage" refers to all output stage components in the entire transmitter.
You can use the Setup window to define the desired output power.
Note In order to set the output power, the transmitter must be delivering power.
1. Press the ON key on the transmitter.
2. Select Transmitter > Output Stage > Setup .
The Output Stage > Setup window opens.
3. Change the value under Nominal Power to the desired transmitter output power.
This establishes the reference value for the warning and fault thresholds.
4. Change the percentage at Ref. Voltage in increments of 1 % until the desired power
( Forward Power ) is approximately reached (measured via built-in checkpoint or exter-
nal measuring instrument).
For fine adjustment of the power setting, you can change the percentage under Ref.
Voltage in 0.1% increments.
Display/setting item Description
Forward Power Present forward power of the transmitter
Nominal Power Nominal power of the transmitter (cannot be modified)
Actual Ref. Voltage Present value of the reference Voltage
RF Warning Limit Warning threshold for the forward power referenced to nominal power. A
warning is given if the value drops below the threshold.
RF Fail Limit Fault threshold for the forward power referenced to nominal power. A
fault message is displayed if the value drops below the threshold.
