Anritsu’s MS2760A and MS2762A Spectrum Master modules.

Anritsu’s Spectrum Master MS276xA compact spectrum analyzer frequency band climbs to 170 GHz

  • Anritsu enhances its Spectrum Master MS2760A modular spectrum analyzer range by adding two models offering frequency coverage from 9 kHz to 145 GHz and 170 GHz.
  • The new modules in the Spectrum Master MS2762A range, which according to the models cover eight frequency bands (6 GHz to 32 GHz up to 6 GHz to 170 GHz), are designed for applications requiring higher sensitivity.

This family of frontless modules controlled via a tablet or PC via a USB link perform traditional spectral measurements, such as channel power, occupied bandwidth, adjacent channel power and harmonic measurements on continuous signals (CW).

These two families of Spectrum Master MS276xA spectrum analyzers, covering a frequency band up to 145 and 170 GHz, can perform the spectral measurements required by applications operating in the millimeter frequency range.

The two new Spectrum Master MS2760A models and the eight MS2762A models have a typical measurement dynamic range of 108 dB at 70 GHz. The Spectrum Master MS2762A modules display a typical Displayed Average Noise Level (DANL) of about -141 dBm from 6 GHz to 90 GHz. They cover the frequency bands starting from midway through the C band
all the way through the E band. Above 90 GHz, Anritsu reports that typical DANL performance remains above -136 dBm/Hz to 110 GHz, -129 dBm/Hz between 110 and 145 GHz, and -122 dBm/Hz between 145 and 170 GHz.

These analysers have an amplitude accuracy of typically ±1 dB and a sweep speed of less than 24 seconds (typical value, depending on processor speed) over the entire frequency range of 6 GHz to 170 GHz.

According to the Japanese manufacturer, their compact construction improves accuracy and sensitivity for measurements in the millimeter wave band because these USB spectrum analyzers can be connected directly to the device under test (DUT). It is therefore not necessary to calibrate external mixers or modify parameters to see a different frequency band. The elimination of external mixers also simplifies test setup and measurement.

With a USB extender, antenna measurements or wave path losses can be performed remotely.
