Perform a Full 2-Port Calibration (SOLT: Short, Open, Load, Through) at the exact plane where the amplifier will be connected.
Allow both the VNA and the amplifier to reach thermal equilibrium (typically 15–30 minutes) for stable measurements. 2. Calibration (The Foundation)
Most VNAs have a low damage threshold (e.g., +20 dBm). If your amplifier outputs more power than this, place a high-power fixed attenuator on the output side before connecting it to the VNA Port 2.
Once calibrated and connected, you focus on the four primary S-parameters:
By performing a Power Sweep at a fixed frequency, you find the input power level where the gain drops by 1dB. This defines the limit of the linear range.
This shows the amplifier's gain across the frequency sweep. Look for "flatness" (minimal variation) over the desired bandwidth.
Indicates how well the input impedance matches the system (usually 50Ω). A lower S11 (e.g., < -10 dB) means less power is reflected back to the source.
A VNA measures the "system," so you must calibrate to remove the effects of cables and adapters. |
What users are saying
Â
Just a note to compliment you on creating the best and most complete slide
show software on the market.
Â
I am a professional entertainer who includes movie trivia and more in my karaoke
shows as well as trivia games on DVDs that I do at children's parties. I
have tried every slide program available from those requiring special viewers to
those that produce flash slide shows. However, I have never found one as
complete and well written as yours.
Â
You have definitely covered all bases and I just want to say thanks for a great
product.

MySlideShow Gold - Timeline Editor
 MySlideShow
v3 always synchronizes slides with the Sync Playlist (accessible by the
Sound button). The best way to make a custom synchronization of your slides
with audio is to use the Timeline Editor included in MySlideShow Gold. To
open the Timeline Editor, select the Timeline tab of the Slide List. There
you can define slide transition points on the timeline of the Sync Playlist.
The Timeline view allows you to
play the music, drag slides on the timeline or select a slide group and
automatically allocate them on a part of the timeline (for example: a song in
the playlist). The synchronization options and Timeline Editor allow you to
create a slideshow which advances the slides in the same points in the
preview/.exe mode and output video files or DVD discs.
