3. Minor improvements have been made to the user interface for disk operations. The file last
selected on the disk directory page is remembered when the user selects SAVE/RECALL. If
the user tries to save a file to the internal disk drive when the disk has been removed, the
internal disk drive remains the selected drive.
4. Waveguide delay can now be selected by pressing [SCALE) ELECTRICAL DELAY
The dump-graphics feature, previously added as a carry-over from the 872OC, can be
selected by pressing I-J ,~ERVJCE'MENU: ,TEST^ .OPT$NS DUMP GRAPH
be toggled between on and off, which enables/disables the dumping of the graphical output
during the System Verification service tests (SYS VER TESTS).
6. The SELL (set learn string revision) command has been updated to work with post 5.00
revisions (HP 8753D including Option 011). The current HP 875x can now generate and
receive instrument learn strings from all the previous shipment releases. Disk compatibility
between the various HP 8753 revisions and the current revision is now supported.
7. The following are the choices from the new CONFIGURE menu, selected by pressing
. RAW OFFSET Toggles attenuator and sampler cal offsets on or off.
. SPUR AVOID Toggles spur avoidance on or off. HP 8753D (including Option 011)
New Enhancements and Features.
The following enhancements and features are new in firmware revision 6.12:
1. The capability to store S-parameter data to component data files using the "Touchstone"
format (S2P) has been added.
2. A new IF bandwidth filter setting of 3700 Hz has been added.
3. The individual power ranges will now allow 3 dl3 over and under the values shown with
each power range selection.
4. Enhancements have been made to the file naming capability for files generated by the
instrument during execution of a sequence. The new menu can be found by pressing
( / _)
FILE UTILITIES SEQUENCE FILENAMING
SAVE RECALL
a new softkey to support the inclusion of the sequence loop counter in the filenames.
5. A method of external calibration, ' Ihke 4 mode, provides a remote-only command that
directs the network analyzer to take a single "group" or sweep (consisting of a forward
and reverse sweep) and to collect the raw data for all 4 S-parameters. The user can then
extract the raw data for the S-parameters (or the pre-raw data, which has not had sampler
correction nor attenuator offsets applied) and perform the error correction in an external
computer (using previously extracted calibration arrays).
6. A new feature, Adapter Removal, is designed for cases where the device under test is
"non-insertable" and thus an adapter is required. This feature requires two full 2-port
calibrations, one for each port, and subsequently provides a calibration for the test device
with the effects of the adapter removed. The menu is found by pressing m MORE
