Operation

 

 

Using the Mixers with MMS Analyzers

CONV LOSS

 

 

(conversion loss)

Offsets the reference level to compensate for amplitude losses at

 

the active input port. If necessary, use select input to activate the

 

desired input port before specifying its conversion-loss offset.

 

To clear the offset, enter a conversion loss of zero.

 

After the instrument preset, a default value of 30 dB is activated

 

automatically for the input port of the external-mixer-interface

 

module.

 

Preset Input

Sets which active input port will be selected when the INSTR

 

PRESET is pressed. The preset input softkey can be accessed by

 

pressing State, then MORE.

INSTR PRESET

Resets to the preset input and to the lowest full frequency range

 

available. (For an external mixer, this is band A.) This is a front

 

panel key.

 

SIGNAL IDENT

 

 

(signal identify)

Press Frequency, More, sig id options.

 

Executes a routine to identify real, in-band signals using either

 

the image (default) or shift methods.

 

Several options are available under sig id options:

- SIG ID

CF

Places the marker on the identified real signal and

 

 

centers the signal on the display.

-SIG ID MAN OFF Selects manual or automatic (default) mode.

-IMAGE/SHIFT Selects the routine to use for identification.

-SIG ID AMPTD Specifies the amplitude difference between the marked signal and signals tested as images or harmonics (default is 10 dB; applies only to IMAGE mode.)

-IMAGE N START Determines the frequency range for possible image or harmonic responses by selecting the lowest and highest local oscillator harmonic used for mixing, according to the tuning equation below:

Fs = N x FLO ± IF

Default is 1.

-IMAGE N STOP See “IMAGE N START” definition above. Default is 40.
