Basic Signal Generator Operations
output. In this mode, a power meter is required to measure the output of the signal generator
and assist in achieving the required output power at the point of detection.
To set the signal generator to the ALC off mode, follow these steps:
1. Press
Preset.
2. Press
Frequency, enter the required frequency, and terminate the entry with the
appropriate terminator softkey.
3. Press Amplitude, enter the required amplitude, and terminate the entry with the
appropriate terminator softkey.
4. Press
RF On/Off.
5. Press
Amplitude > ALC Off On.
This deactivates the signal generator’s automatic leveling control.
6. Monitor the RF output amplitude as measured by the power meter.
7. Press
Amplitude and adjust the signal generator’s RF output amplitude until the desired
power is measured by the power meter.
Power Search Mode
Power search mode executes a power search routine that temporarily activates the ALC,
calibrates the power of the current RF output, and then disconnects the ALC circuitry.
To set the signal generator to manual fixed power search mode, follow these steps:
1. Press
Preset.
2. Press
Frequency, enter the required frequency, and terminate the entry with the
appropriate terminator softkey.
3. Press Amplitude, enter the required amplitude, and terminate the entry with the
appropriate terminator softkey.
4. Press ALC Off On.
This deactivates the ALC circuitry.
5. Press
RF On/Off.
6. Press
Do Power Search.
This executes the manual fixed power search routine.
There are two power search modes: manual and automatic.
When
Power Search Manual Auto is set to Manual, pressing Do Power Search executes the power
