10-6 CHARACTERIZATION
FILES Before performing an AutoCal on a 37xxxE, the Characterization File
for the AutoCal Module has to be loaded. This file may be recalled
from the USB drive accompanying the Module. It may also be recalled
from one generated using the user's specialized manual calibration.
Insert the AutoCal Module Characterization USB drive into the USB
port. Press the Utility Menu key (left), then select the following menu
options, in turn: AUTOCAL UTILITIES, RECALL FROM USB
DRIVE. Select the file "Lxxxxxx.ACD".
If a copy of the Characterization File is in the SD Card, you can recall
it by choosing RECALL FROM SD CARD instead. Select the same
file "Lxxxxxx.ACD".
NOTE
The “xxxxxx” in the above paragraphs correspond to the
serial number of the AutoCal module.
Should you desire to re-characterize the module, which is recom-
mended every six months of usage, perform the following procedure:
Step 1. Using a 365x or 375x Calibration Kit, perform a
12-Term calibration over the desired frequency range
of characterization, but within the range of the
AutoCal module and the VNA.
NOTE
Any calibration method may be used (Stan-
dard, Offset Short, LRL/LRM, or TRM)
along with either the Coaxial or Waveguide
line types.
Step 2. Upon completion of the calibration, press the Utility
Menu key.
