Chapter 4, Description of Fields

Fields

Firmware

This field displays the current firmware revision for your Test Set. The revision number is automatically changed when updated firmware is installed.

Screens Where Field is Present

CONFIGURE

Flow Cntl

This field selects from the following choices of flow control for the Serial Port currently selected.

None disables the Xon/Xoff function.

Xon/Xoff lets the Test Set “talk/listen” to the transceiver to alter the rate of the data being sent.

Hardware uses the serial port’s RTS and CTS lines to transfer data at high baud rates.

Operating Considerations

This setting is retained when the Test Set is turned off.

Baud rates of 38400 and above must use Hardware flow control.

Screens Where Field is Present

I/O CONFIGURE

FM Coupling

This field alters the FM modulator to allow DCFM from internal and external modulation sources. This field also selects ac or dc coupling between the RF Generator’s frequency modulator and the rear-panel MODULATION INPUT connector.

Operating Considerations

This field should be set to DC whenever the AFGen2 To field is set to FM; this provides better modulation response at low data rates.

Screens Where Field is Present
