3GHz ruggedized battery-powered spectrum analyser

Author: EIS Release Date: Feb 15, 2023

Anritsu has introduced a portable 3GHz spectrum analyser with a 10inch display, measuring 290 x 212 x 96mm and 3.8kg for field, lab and manufacturing use.

MS2070A has a dynamic range over 105dB at 2.4GHz and the optional pre-amplifier takes typical DANL to from -150dBm to -167dBm, coupled with a third-order intercept +11dBm. Typical level accuracy is ±0.5dB.

 

“It can conduct basic transmitter testing, as well as interference hunting,” according to the company. “Cellular network operators can configure it with a PIM stick for PIM hunting as well. In lab and manufacturing environments, the MS2070A can be used for standard RF measurements.”

 

Frequency sweep is up to 32GHz/s and measurements for occupied bandwidth, channel power and adjacent channel power come as standard.

 

A zero span displays TDD and pulsed signals with resolution bandwidth of 10Hz to 5MHz for measurements of power over time, and spectrograms are also standard for detection of intermittent interferers.

 

“As many as 6 traces can be set simultaneously with different detectors. Averaging can be applied to each, as well,” said Anritsu. “Up to 12 markers are provided, so signals of interest can be highlighted and monitored how they vary over time, relative to themselves and other signals.”

 

Alerts for new interfering or lost signals are generated automatically and, for long-term spectrum monitoring, there is are upper, lower, envelope and alarm limits.

 

The 1,280 x 800 multi-touch display is IK08-rated, and “common functions are always accessible and side menus collapse to maximise graphical results”, said Anritsu.

 

Anritsu MS2070A spectrum analyser portsEthernet and USB interfaces are standard, and Wi-Fi 802.11b/g/a/n is an option, and the optional GNSS reception can cover GPS, Galileo, Glonass and BeiDou so long as an external antenna is connected.

 

When the instrument is in its soft carry case, environmental protection is to IP52, and the RF input is protected up to 5W of RF.

 

Battery life is said to be three hours, extending to six with an add-on power pack.
