2 port Network Analyzer:
PocketVNA has two ports, where port 1 is the output. Port 1 measures the reflected signal (S11) and port 2 the transmitted signal (S21).
You can perform measurements at least from 500 kHz to 4 GHz. Measurements slightly outside this region (such as 400 kHz or 4.2 GHz) might be possible but are not guaranteed. Please contact us if you want to perform measurements outside the specified frequency range.
Typical range is up to -70dB @50MHz and up to -40dB @4 GHz
Dynamic range varies over frequency and depends on scan and calibration parameters such as averaging factor or smoothing.
Resulting from the dynamic range, impedance can be typically measured from 3 to than 1000 ohm. For most frequency ranges this range will be larger.
Measurement is much lower than any lab scale equipment.
A normal scan takes about 10 ms per data point plus USB communication. As an example a 1001 points scan S11 only takes 12 seconds. By using averaging to improve resolution, speed can significantly increase. I f you measure all parameters (S11, S12, S21, S22) at the same time, measuremnt time is four times higher!
Number of steps:
From 1 to 10001; Basically, maximum number of steps is mainly limited by the available measurement time. A 10001 steps scan take about 2 minutes.
1 Hz; For example you can scan from 1MHz to 1.001MHz in 1001 steps.
< 500mA; typically 400 mA
(length x width x height): 90mm x 64 mm x 26mm (about 3.5" x 2.5" x 1")
PocketVNA is a research tool for laboratory usage only. Keep away from humid or hazardous places. Always read the manual and safety instructions prior before using the pocketVNA.
