14. Reference	This field selects the external reference frequency that the instrument locks to, and
	sets the reference tuning mode.
	Choices	13 MHz
		10 MHz
		5 MHz
		2 MHz
		1 MHz
		Normal locks the instrument to the external reference frequency
		selected.
		Tunable enables the instrument to adjust its internal frequency
		reference. Frequency adjustment is relative to an external
		reference which the internal reference is calibrated to.
		Calibrate calibrates the internal reference to the external reference
		for use in Tunable mode.
15. RF IN/Out	This field is used to indicate losses or gains between the RF IN/OUT port and the
	device under test.
NOTE	This field is only used when the RF Level Offset field is set to On.

•Enter apositive value to indicate a gain (such as an amplifier gain). When the RF IN/OUT port is used as an output, the RF Generator level is automatically set to that amount below which is indicated in the RF Generator’s Amplitude field.

(Example; if this value is 10 dB, and the Amplitude field shows 0 dBm, the actual level out this port is −10 dBm.)

When this port is used as an input, the CW Power, Peak TX Power, measurements, and Spectrum Analyzer Marker Level (Lvl), are automatically reduced.

•Enter a negative value to indicate a loss (such as cable loss). The RF Generator level out this port is automatically set to that amount above which is indicated in the RF Generator’s Amplitude field to compensate.

When used as an input, the CW Power, PK TX Power, Fast TX Carrier Power measurements, and Spectrum Analyzer Marker (Lvl), are increased.

16.RFGen Volts This field selects between 50 ohm and emf voltage units for the RF generator amplitude settings.
