Notes
Vector Network
Analyzer Release 2.0.2591.24355 Executable name: VNAR3
Latest stable release.
Vector Network
Analyzer Beta 2.1.3192.40899
Executable
name: VNAR3
2.1.6 (build 3192.40899)
adds detection of an apparent unshielded S21 receive measurement. Because the
VNA uses a broadband detector, if the device under test is not well shielded an
external interference source can contaminate S21 measurements at all
frequencies rather than just near the frequency of the interfering source. A
caution note is placed on the screen when showing S21 measurements if the
receive detector appears to be detecting excess noise ingress.
2.1.5 (build 3181.21991)
adds a menu item to change the background color. This may be useful if you want
to capture screenshots directly from the CRT for use as a graphic in some other
document or application and the color your system [Inactive::Captiontext]
has chosen doesn’t show up well.
Additionally, a power-saving mode has been added to
the target code. This powers down the I- and Q- DAC
multipliers in the VNA hardware when it is not sweeping, and re-enables them
for each sweep. This results in a significant power reduction of the DDS chip
when idle. If the instrument is continually sweeping it won’t make as much
difference. The VNA still puts out full-strength signal after it’s done with a
sweep at the last swept frequency (handy as a quick signal generator).
2.1.4 (build 3150.38355)
adds another Export CSV Rectangular menu item to allow two options:
Export CSV Rectangular (North American format), and
Export CSV Rectangular (European format).
The North American/UK, and
European versions of Excel use different CSV file separator characters. The two
menu items allows generating files compatible with
either version.
2.1.3 (build 3141.37297)
improves exception handling, provides anti-aliasing of traces on the display, and
slightly improved graphics updating (fewer screen redraws). This assembly
includes a ‘strong name’ as a security enhancement. The program assembly is
digitally signed using a private key. The public key used to check the
signature validity is included within the assembly. The Microsoft loader will
automatically validate the signature, if it’s OK the application will launch
normally, if the signature check fails, the application will abort immediately
with an ‘this application has encountered an error’ box.
This check helps protect against bit-level changes or alterations of the
executable file.
2.1.3 (build 3069.24376)
very slightly improves the detector calibration convergence. Not worth updating
unless you have problems with 2.1.2 or earlier converging.
2.1.2 (build 3053.25751)
adds 0.5 dB/division display setting, and reorganizes the vertical menu into
several sub menus to save screen height. It creates a new file version (1.0.5)
for the saved measurement file, but can read (1.0.4) as well.
2.1.1 Added R+jX display
modes.
2.1.x is a BETA Version of software. It requires
that a new Detector Calibration be run. Detector Calibration is compatible with
the different 2.1 beta versions, so you will only need to run it again if you
get an error message. The possibility exists that the detector calibration may
not converge for every unit, but I’ve not received any errors lately. If your
1meter cal cable is less than ~ 0.9 meters long, it might not converge.
Vector Network
Analyzer Release 1.6.2416.21766 Executable name: VNAR3
Older release.
Signal Generator
Software Release 2.0 Executable
name: SGENR2
August 8 update provides a ‘strong name’ of the
assembly as a security enhancement. No functional changes from the January 31
update.
January 31 update changes the Installer to fix
incorrect prerequisite (executable is unchanged). Ported to
NET 2.0. Fixes a bug where the
phase meter had a 180 degree error (sign flip). Also adds the ability to
compensate for the VNA internal crystal oscillator error. The oscillator still
drifts with temperature, but this cal reduces the fixed error a lot. The
existing SGEN data file is not compatible, and the application will warn to
reset the external / internal and oscillator compensation options. The new
version is called SGENR2, the old one was called
SGENR1.
Signal Generator
Software Release 1.1 Executable
name: SGENR1
Older Release. Lower frequency limit decreased
down to 2,000 Hz. There is a high-pass pole at 50 KHz, so the output level
starts decreasing (by 3 dB) at 50 KHz. The output waveform becomes very distorted below 25 KHz.
