Spectrum Master™ MS2720T Spectrum Analyzer Features

AM/FM/PM Analyzer (Option 0509)

AM/FM/PM Analyzer

Spectrum Master comes with AM/FM/SSB audio demodulation

as standard. By adding Option 509, the instrument becomes

capable of measuring, analyzing, and displaying key

modulation parameters of the RF Spectrum, Audio Spectrum,

Audio Waveform and even includes a 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.

• An Audio Waveform oscilloscope display is included

with all three demodulation formats that shows the

time-domain demodulated waveform.

• The Demodulation Summary display shows all of the

RF and demodulation parameters for each modulation

format on one screen.

• Zero Span IF Output (Option 89) provides an IF

Output signal centered at 140 MHz with bandwidth

up to 32 MHz.

Secure Data Operation (Option 7)

For highly secure data handling requirements, this software

option prevents the storing of measurement setup or data

information onto any internal file storage location. Instead,

setup and measurement information is stored only to the

external USB memory location. A simple factory default reset

prepares the Spectrum Master for transportation while the

USB memory remains behind in the secure environment. The

Spectrum Master cannot be switched between secure and

non-secure operation by the user once configured for secure

data operation.

Light Weight

Weighing about 3.8 kg (8.5 lb) fully loaded, including a Li-Ion

battery, this fully functional handheld spectrum analyzer is light

enough to take anywhere, including up a tower.
