Hardkey and Softkey Reference
MEMORY. displays the trace memory for the active channel. This is the only memory display mode where the
smoothing of the memory trace can be changed. If no data has been stored in memory for this channel, a warning
message is displayed.
MEMORY1. causes memory 1 to be the active memory.
MEMORY2. causes memory 2 to be the active memory.
MEMORY1 → 2. copies the contents of memory 1 into memory 2.
MEMORY2 → 1. copies the contents of memory 2 into memory 1.
MIDDLE VALUE. sets the midpoint for DELTA LIMITS. It uses the entry controls to set a specified amplitude value
vertically centered between the limits.
MIN. moves the active marker to the minimum point on the trace.
MINIMUM BANDWIDTH. sets the minimum bandwidth value of the bandwidth test limits.
MINIMUM FREQUENCY . is used to: 1) define the lowest frequency at which a calibration kit standard can be used
during measurement calibration. In waveguide, this must be the lower cutoff frequency of the standard, so that the
analyzer can calculate dispersive effects correctly (see OFFSET DELAY). or 2) set the minimum frequency of the
selected frequency band when setting up ripple test parameters.
MKR SEARCH [ ]. leads to the marker search menu, which is used to search the trace for a particular value or
bandwidth.
MKR ZERO. puts a fixed reference marker at the present active marker position, and makes the fixed marker stimulus
and response values at that position equal to zero. All subsequent stimulus and response values of the active marker
are then read out relative to the fixed marker. The fixed marker is shown on the display as a small triangle ∆ (delta),
smaller than the inactive marker triangles. The softkey label changes from MKR ZERO to MKR ZERO ∆REF = ∆ and
the notation “∆REF = ∆” is displayed at the top right corner of the graticule. Marker zero is canceled by turning delta
mode off in the delta marker menu or turning all the markers off with the ALL OFF softkey.
MODIFY [ ]. leads to the modify cal kit menu, where a default cal kit can be user-modified.
MODIFY COLORS. present a menu for color modification of display elements. Refer to the user’s guide for information
on modifying display elements.
MODIFY: FRESNEL. leads to a menu used to modify the Fresnel reflection model coefficient.
MODIFY: REFLECTOR. leads to a menu used to modify the reflector model coefficient.
MODIFY: THRU. leads to a menu used to modify the optical thru model coefficient.
MORE RANGES. provides access to more power ranges.
N 50Ω 85054. selects the 85054 cal kit.
N 50Ω 85032F. selects the 85032F cal kit.
N 75Ω 85036. selects the 85036B/E cal kit.
N DB POINTS. sets the N dB point which is used to determine the bandwidth test cutoff frequencies. Enter the number
of decibels below the peak of the bandpass that the filter is specified.
NETWORK ANALYZER. sets the analyzer to network analyzer mode.
NEW SEQ/MODIFY SEQ. activates the sequence edit mode and presents the new/modify sequence menu with a list of
sequences that can be created or modified.
NEWLINE. puts a new line command into the display title.
NEXT PAGE. steps forward through a tabular list of data page-by-page.
NUMBER OF GROUPS. triggers a user-specified number of sweeps, and returns to the hold mode. This function can be
used to override the test set hold mode (indicated by the notation “tsH” at the left of the screen). In this mode, the
electro-mechanical transfer switch and attenuator are not protected against unwanted continuous switching. This
occurs in a full two-port calibration, in a measurement of two different parameters that require power out from both
ports, or when the channels are uncoupled and a different power level is set for each channel. If averaging is on, the
number of groups should be at least equal to the averaging factor selected to allow measurement of a fully averaged
trace. Entering a number of groups resets the averaging counter to 1.
NUMBER of POINTS. is used to select the number of data points per sweep to be measured and displayed. Using fewer
