Anritsu unveils spectrum analyzer
Anritsu Co. introduced the MS2711D Spectrum Master, a handheld spectrum analyzer that delivers improved sweep speed and is designed with a built-in pre-amp that increases the analyzer’s sensitivity and dynamic range.
The MS2711D, which covers a specified range of 100 kHz to 3.0 GHz, has an industry-best = -135 dBm noise floor, Anritsu says. Full span sweeps from 9 kHz to 3 GHz can be performed in </=1.1 seconds, while the sweep speed in zero span can be set from <50 ms up to 20 seconds.
The MS2711D’s AM/FM/SSB demodulator further improves a user’s ability to identify interfering signals.
Another benefit of the MS2711D is its ability to tolerate input signals up to +43 dBm without any damage. Complementing this capability is the spectrum analyzer’s dynamic attenuation feature, which tracks the input signal level and automatically adjusts the input attenuation level to protect the MS2711D in the performance of high RF signal levels.
Taking advantage of the Spectrum Master design, the MS2711D has a simple multilingual user interface that allows key measurements to be made with a single button. Among the one-button measurements are field strength, channel power, occupied bandwidth, adjacent channel power ratio (ACPR), carrier-to-interference ratio (C/I), and interference analysis. A full range of marker functions — including peak, center, and delta are available with the MS2711D.
The MS2711D has been designed to withstand the harsh environments and terrain associated with field use. It weighs less than five pounds and features a large high-resolution LCD display as well as an optional color display.
The MS2711D measurement capability can be expanded through an optional power measurement feature, and an optional transmission measurement capability that allows a user to view the frequency response characteristics of two-port frequency devices. An optional internal bias T is also available to drive active devices-under-test such as amplifiers.
Priced from $6,350, the MS2711D is available for delivery in four to eight weeks.
New Site Master family introduced
Anritsu Co. also introduced the S331D and S332D Site Master cable and antenna analyzers that feature a number of improvements in performance and operation to conduct accurate return loss/SWR, cable loss, and Distance-to-Fault (DTF) measurements on wireless networks.
With a measurement range of 25 MHz to 4 GHz, the S331D/S332D cover all cell site frequency ranges without additional plug-ins or modules required. They feature industry-best immunity-to-interference of +17 dBm on-channel and -5 dBm on-frequency, so that accurate and repeatable measurements can be made in high RF-noise environments.
They also feature increased sweep speed of <500 msec per sweep that enables easier identification of intermittent, real-time problems. Distance measurement resolution and fault location are optimized by the models’ 130, 259, and 517 data points.
The S331D/S332D are easy to operate. New one-button measurement capabilities include interference analysis and carrier-to-interference ratio. (C/I). As many as 70 signal standards are built into the S331D/S332D, which further simplifies measurements by eliminating the need to perform channel-to-frequency translation.
For applications needing analysis of over-the-air interference and transmitter characteristics, the S332D adds a full range of spectrum analysis capabilities to the cable and antenna analysis capabilities. With amplitude sensitivity of <-135 dBm, the S332D can examine low-level interference and reverse link signals.
The S331D/S332D feature the Site Master design, which includes a rugged and reliable chassis, intuitive soft key menu, multilingual user interface, and large high-resolution display.
Anritsu also offers an optional color display with the S331D/S332D. Both models weigh less than five pounds and measure 10W × 7H × 2.4D (inches).
The S331D is priced at $6,950 while the S332D is $10,000. Delivery is four to eight weeks.
