Hardkey and Softkey Reference
MARKER all OFF. turns off all the markers and the delta reference marker, as well as the tracking and bandwidth
functions that are accessed with the MKR FCTN key.
Marker Fctn. key activates a marker if one is not already active, and provides access to additional marker functions.
These can be used to quickly change the measurement parameters, to search the trace for specified information, and to
analyze the trace statistically.
MARKER MODE MENU. provides access to the marker mode menu, where several marker modes can be selected
including special markers for polar and Smith chart formats.
MARKERS: CONTINUOUS. located under the Marker key, interpolates between measured points to allow the markers to
be placed at any point on the trace. Displayed marker values are also interpolated. This is the default marker mode.
MARKERS: COUPLED. couples the marker stimulus values for the two display channels. Even if the stimulus is
uncoupled and two sets of stimulus values are shown, the markers track the same stimulus values on each channel as
long as they are within the displayed stimulus range.
MARKERS: DISCRETE. places markers only on measured trace points determined by the stimulus settings.
MARKERS: UNCOUPLED. allows the marker stimulus values to be controlled independently on each channel.
MATH: DATA/MEM. divides the data by the memory, normalizing the data to the memory, and displays the result. This is
useful for ratio comparison of two traces, for instance in measurements of gain or attenuation.
MATH: DATA - MEM. subtracts the memory from the data. The vector subtraction is performed on the complex data.
This is appropriate for storing a measured vector error, for example directivity, and later subtracting it from the device
measurement.
MATH: DATA * MEM. multiplies memory and data.
MATH: DATA + MEM. adds memory and data.
MATH: MEM / DATA . divides memory by data. This operation normalizes the memory to the data. This is useful for ratio
comparison of two traces, for instance in measurements of gain or attenuation.
MATH: MEM - DATA . subtracts memory from data.
MATH: MEM1 / MEM2 . divides memory 1 by memory 2.
MATH: MEM1 - MEM2 . subtracts memory 2 from memory 1.
MATH: MEM1 * MEM2 . multiplies memory 1 and memory 2.
MATH: MEM1 + MEM2 . adds memory 1 and memory 2.
MATH: MEM2 / MEM1 . divides memory 2 by memory 1.
MATH: MEM2 - MEM1 . subtracts memory 1 from memory 2.
MAX. moves the active marker to the maximum point on the trace.
MAXIMUM BANDWIDTH. sets the maximum bandwidth value of the bandwidth test limits.
MAXIMUM FREQUENCY. is used to: 1) define the highest frequency at which a calibration kit standard can be used
during measurement calibration. In waveguide, this is normally the upper cutoff frequency of the standard. or 2) set
the maximum frequency of the selected frequency band when setting up ripple test parameters.
MAXIMUM RIPPLE. sets the maximum ripple allowed of the selected frequency band. The maximum allowable ripple is
100 dB.
Marker Search. allows user to turn tracking on, off and search for the maximum, minimum, bandwidth, and target
points on the trace.
Meas. key provides access to a series of lightwave measurements and a softkey menus for selecting the electrical
parameters or inputs to be measured.
MEASURE RESTART. aborts the sweep in progress, then restarts the measurement. This can be used to update a
measurement following an adjustment of the device under test. When a full two-port calibration is in use, the
MEASURE RESTART key will initiate another update of both forward and reverse data. This softkey will also override
the test set hold mode, which inhibits continuous switching of either the test port transfer switch or step attenuator.
This softkey will override the test set hold mode for one measurement. If the analyzer is taking a number of groups, the
sweep counter is reset at 1. If averaging is on, MEASURE RESTART resets the sweep-to-sweep averaging and is
effectively the same as AVERAGING RESTART. If the sweep trigger is in HOLD mode, MEASURE RESTART
executes a single sweep.
