RF Generator Field Definitions
RF Freq
Sets the RF Output frequency of the Test Set RF Generator. Units of measure are GHz, MHz,
kHz and Hz as defined by user.
Level
Sets the RF Generator Output Level. The selected RF Output level is dependent on the RF
Output port selected. Refer to 3900 Platform Specifications
for the correct output. The indicated
RF output is modified if an RF Level Offset value is set. Units of measure are dBm, V and dBμV.
Freq Inc
Defines the RF Output Frequency incremental change value. This is the value by which the RF
Output Frequency is changed when the [INC Gen Freq] / [DEC Gen Freq]
soft keys are used.
Units of measure are GHz, MHz, kHz and Hz as defined by user.
Level Inc
Defines the RF Output Level incremental change value in dB. This value is applied to the RF
Output Level when the [INC Gen Level] / [DEC Gen Level]
soft keys are pressed.
Dx Offset
Defines the Duplex Offset frequency value. The frequency value set here indicates the
difference between the RF Generator output and the RF Analyzer input when the
[Gen Freq = Ana Freq + Dx Offset] Soft Key
soft key is active. Units of measure are MHz, kHz
and Hz as defined by user.
Mod (Modulation)
Selects the type of modulation applied to the RF Output Signal.
Information Flags
EMF or PD
The RF Output Level unit of measurement is Volts, the value can be displayed as EMF or PD.
EMF or PD is selected from the Ports Configuration Tile
. The selected value is displayed
adjacent to the set Level field on the Generators Tile (refer to Fig. 8-19).
Fig. 8-19 EMF and PD Indicators
Offset Enabled
Offsets are enabled and disabled from the RF Limits Configuration Tile. When an offset is
enabled, the warning symbol is shown beside the measurement.
RF OFF
When the [RF Gen] Soft Key soft key is set to OFF, an RF OFF indicator is shown on the
Generators Tile.
