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.

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.
