Triarchy VSA6G2A - 6.2 GHz USB Vector Spectrum Analyzer

The VSAG2A is a very cost effective USB vector spectrum analyzer. It can do most of the basic test functions a regular sized spectrum analyzer can do. The VSAG2A is very tiny instrument, but it can cover very wide measurement range.

The frequency up to 6.2G, power up to 28 dBm, noise level low as -140dBm. The test data will be displayed with level, linearity and frequency calibrated.

VSAG2A is very suitable for field test. Because it is very small and easy to be carried, it can be used as device to monitor RF signal. It can also suitable for the EMC test with near field antenna.

VSA PC Application Overview

1. Utility keys - Allows user to access the system level function. Function detail will be shown on second function keys
2. Display Function keys - Click the Display Function keys, it will be shown accordingly display function such as Current, MAX or density.
3. Main Display area - This area will display signal spectrum waveform, and also shown density and waterfall of signal spectrum. This area will be shown signal demodulation waveform such as EVM, eye diagram, constellation. The image can be moving by keep hold left key of mouser and moving the mouser.
4. Status block - Status block shows the main parameter setting for signal spectrum measurement: such as frequency, amplitude, RBW, sweep and working mode.
5. Second functions keys - Second function keys will extend secondary functions relative to the primary function keys and utility key. It is similar to soft key in most of equipment which is location on side of screen.
6. Function keys
   Most of major equipment settings are done by the Function keys.
   General setting for Spectrum analyzer will be:
   Input Frequency, Span, amplitude. Then measured RF signal will be shown properly at display area.
   General setting for demodulation will be:
   Select Demodulation method and turn on it, go into Demod setup key to do more operation.
7. Digital input keys - Digital input keys will input digital and units for frequency, amplitude and timing. This standalone input key is similar to desktop equipment.
8. USB connection area - When VSA6G2A/B is plugged in the PC, USB connection area will display the product model name, S/N and connection status.
