View Array Master Menu/View Array Interpol Menu

hese keys allow you to view the actual calibration data arrays that are currently in use. he
arrays are copied into a memory trace for easy analysis. his allows you to scale them, and use
markers to read out actual values.
: Displays the directivity cal array as a memory trace. his is related to the
Directivity
raw directivity of the analyzer but it does not equal it. he raw directivity is determined by
dividing the tracking array below by this directivity array.
: Displays the source match cal array as a memory trace. his is the raw (or
ource Match
uncorrected A/R) source match of POR 1.
: Displays the tracking (narrowband frequency response of coupler with 100%
Tracking
re ection) cal array as a memory trace.

a memory trace.
: Displays the broadband R* frequency response cal array as a memory

Miscellaneous Service Functions

Clearing Nonvolatile Memory (S AM)
his is also referred to as \zeroing" the nonvolatile SRAM, because the procedure causes the
analyzer to write zeroes into the nonvolatile SRAM locations in memory. Note that this will
erase any les saved to internal memory (NON-VOL RAM disk). his will
constants.
Cycle the the analyzer's power.
After about 8 seconds, the analyzer will emit a double beep. Immediately after this double
beep, press
PRESET
he analyzer will pause after performing the CPU main self-tests and ask if you want to
zero the SRAM. (Note the caution message!) Answer YES by pressing the
softkey #8 (bottom softkey) if you want to continue without clearing the memory.
