1.5 SOFTWARE RELEASE HISTORY
1-4
Equipment supplied consists of the tuner, an accessory kit and an
Installation and Operation Manual (P/N 181629-003).
To fully utilize the tuner, equipment from the following list should be
selected:
1.
VXI vertical (C-size) mainframe.
2.
VXI slot 0 controller.
The initial version of the tuner software is version 00.01.00, released
May 4, 1999.
Version 01.00.00 was released on October 27, 1999. It added the Board
Not Installed bit into the CDE and DDE registers and a test query to tell
which board is not installed. This was added to help the test technicians
debug problems because the code ignores LO unlocks from what it
considers uninstalled boards. It changed identity information to Agilent
Technologies E2730A. In addition, the #CDT and #CSN commands also
changed format, to comply with customer requests. The YIG calibration
routine has been enhanced to help the test technicians calibrate more units
on the first try. The code no longer allows access to the low level
attenuators (ATR and ATI) via the binary command interface. The reason
for this is that they interfered with ATN processing. It fixed a problem
with the changing of the preselector band. When in kHz tuning, it should
have changed at 981.9995 MHz (because the actual 100 Hz resolution
tuned frequency value is rounded to the closest kHz), but it did not change
until 982.0000 MHz. It fixed the 100 Hz resolution lock times. This
eliminated a problem intercepting signals while in the100 Hz tuning mode
because the LO lock times for the 2nd LO were insufficient. Version
01.00.00 code was compiled on a new version of the compiler.
