GPS (Option 0031) requires external GPS antenna
Built-in GPS provides location information (latitude, longitude, altitude) and Universal Time (UT) information for storage
along with trace data so you can later verify that measurements were taken at the right location. The GPS option requires a
separately ordered magnet mount GPS antenna (2000-1528-R or 2000-1652-R), which are configured to mount outside on
a metallic surface. Frequency accuracy is enhanced for the Spectrum Analyzer (on MS203xC models) when Options 0025
Interference Analyzer and 0027 Channel Scanner are engaged and the enhanced accuracy is maintained for up to 3 days after
loss of GPS lock.

Balanced/Differential S-Parameters, 1-port (Option 0077)
As an alternative to a sampling oscilloscope, verifying the performance and identifying discontinuities in high-data-rate
differential cables is now possible with the VNA Master. After a full two-port calibration, connect your differential cable
directly to the two test ports and reveal the S

. With optional time domain, you can convert frequency sweeps to distance. This
capability is especially valuable for applications in high data rate cables where balanced data formats are used to isolate noise
and interference.
AM/FM/PM Demodulation Analyzer (Option 0509) (MS203xC models only)
The VNA Master + Spectrum Analyzer models comes with AM/FM/SSB audio demodulation standard. By adding Option
0509, the instrument becomes capable of measuring, analyzing, and displaying key modulation parameters of RF Spectrum,
Audio Spectrum, Audio Waveform and Demodulation Summary. The RF Spectrum View displays the spectrum analyzer with
carrier power, frequency, and occupied BW. Audio Spectrum shows the demodulated audio spectrum along with the Rate,
RMS deviation, Pk-Pk/2 deviation, SINAD, Total Harmonic Distortion (THD), and Distortion/Total. Each demodulation also
includes an Audio Waveform oscilloscope display that shows the time-domain demodulated waveform. There is a summary
display that provides a display of all the RF and demodulation parameters.
