RF Generator / RF Analyzer (RF Analyzer)

3. Amplitude

This field is the input amplitude to be assumed at the selected RF Analyzer input.

 

The amplitude shown is for the port selected in the RF Input field.

 

Range

RF IN/OUT: 27.9 to +41.0 dBm. AUX RF IN: 58.0 to +20.0

 

 

dBm.

Chapter 3: Specifications

4. Control

This field determines how the RF Analyzer amplitude is selected.

 

Choices

MS TX Lev automatically selects the RF Analyzer amplitude

 

 

based on the level set in TX Level on the Cell Control screen if the

 

 

RF analyzer’s RF input connector selection is RF IN/OUT.

 

 

Manual requires setting the RF Analyzer amplitude using the

 

 

front-panel keys.

5.Do Open Cal This field is displayed only when AGC Mode is closed. When selected, the correct Open/Auto DAC Value for the signal input, using the present RF Analyzer setting, is entered in the Open/Auto Dac Value field.

 

A stable, repeating RF signal is required for open loop calibration.

 

Doing an open loop calibration is useful for establishing an AGC DAC Value to be

 

used when AGC Mode is Open.

6. Frequency

This field sets Frequency when RF Analyzer Hop Mode is set to Non- Hop.

 

Range

10.0 to 1015.0 MHz.

7.Hop Meas Freq This is the frequency entry field for the frequency assumed when making measurements while the RF Analyzer is frequency hopping.

8. Hop Mode

This field selects between the Hop and Non-Hop modes of the RF Analyzer. Hop

 

Mode cannot be set to Non-Hop until Hop Trig is set to Disarm.

 

 

NOTE

Do not make measurements with Hop Mode set to Hop and Hop Trig set to Disarm.

 

 

9. Hop Offset

This field sets the Hop Offset when the RF Analyzer Hop Mode is set to Hop. The

 

frequency offset is applied to all of the frequencies in the RF Analyzer Hop

 

Frequency table when the RF Analyzer is hopping.

 

Range

50.000 to +50.000 kHz.
