8003 Precision Scalar Analyzer
2-4 Manual 20791, Rev. C, June 2001
The
[PRESET]
key selects the default parameters for any currently displayed test parameters.
See Appendix B for a list of default parameters.
SOURCE Control Keypad
The Source Control keys specify the various parameters that will be assigned to the power
source being used for the measurement routine.
The
[START]
key initiates source frequency changes by specifying the desired start, center, or
CW frequencies depending upon the mode of operation. The
[STOP]
key defines the upper
limit of the frequency range of interest.
The
[POWER]
key allows the specification of the power level that the source will output,
and the
[SWEEP TIME]
key sets the sweep time that is to be used for the measurement.
Sensor Input Connectors
These three receptacles, marked A, B and C, interconnect the sensor(s) that will be used for
the measurement routine. One to three sensors can be used for insertion and return loss mea-
surements. See Section 2.9 for a discussion of the usage of single or multiple sensor configura-
tions.
FUNCTION Control Keypad
Control of the measurement functions of the 8003 is initiated by the six keys in this keypad.
Each key, when pressed, will display a top level menu showing the measurement parameters
that can be processed by using the sub-menu label options activated by the softkeys. Descrip-
tions for all six keys can be found in Section 2.5.
The
[MEAS]
key accesses specific functions related to making ratio or comparison measure-
ments with other selected measurements.
The
[SCALE]
key alters the parameters related to graphic presentations of measured data.
These parameters include display scaling, reference level, and position.
The
[DISPLAY]
key controls the display and formatting of all measurements that are taken.
A long series of sub-menus are available to use for precise control of all aspects of the display of
measured data.
The
[CAL]
key activates the CAL menu which contains five different options used for path
calibration, sensor calibration, and for zeroing sensors and bridges.
The
[CURSOR]
key accesses the cursor and marker capability of the 8003. Cursors and
marker functions can be defined and turned on and off with this key.
The
[MEMORY]
key accesses the 8003 store and recall instrument setups. These setups are
stored in non-volatile memory so that they will not be disturbed at power-down.
Power On/Off Switch
This is a push-push switch to control the ac power to the 8003. The ON condition is indicated
by illumination of one or more of the Channel Indicator LEDs.
