HANDHELD MEASURING INSTRUMENTS
SPECTRUM MASTER
MS2721A
100 kHz to 7.1 GHz
High Performance Handheld Spectrum Analyzer
The MS2721A is the first handheld spectrum analyzer to deliver the
ability to measure very low level signals with a displayed average
noise level of ≤ -153 dBm typical @ 1 GHz in a 10 Hz RBW. Coupled
with a wide range of resolution bandwidth choices, you can configure the Spectrum Master to meet your most challenging measurement needs. As the spectrum becomes more and more congested,
the ability to measure low level, closely spaced signals becomes
more and more important not only for interference detection but also
for wireless system planning.
Operating convenience is of paramount important importance when
equipment is used in the field. The input attenuation value can be tied
to the reference level, reducing the number of parameters a field technician may have to set. The RBW/VBW and the span/RBW ratios can
be set to values that are best for the measurements being made, further easing the technician’s burden and reducing the chances of errors. Thousands of traces with names up to 15 characters long may
be saved in the 64 MB non-volatile compact flash memory. These
traces can later be copied into a PC using the built-in USB 2.0 connector or the 10/100 MHz Ethernet connection, or by copying them
to an external Compact Flash card. The MS2721A Spectrum Master
has a very wide dynamic range (>80 dB), allowing measurement of
very small signals in the presence of much larger signals.
Resolution bandwidth and video bandwidth can be independently set
to meet a user’s measurement needs. In addition the input attenuator value can be set by the user and the preamplifier can be turned
on or off as needed. For maximum flexibility, sweep triggering can be
set to free run, or to do a single sweep.
Light Weight
Weighing about six pounds, including a Li-Ion battery, this fully functional handheld spectrum analyzer is light enough to take anywhere,
including up a tower.
With the supplied Remote Access Software you can control an
MS2721A that is miles away, seeing the screen display and operating with an interface that looks exactly like the instrument itself.
The MS2721A features eight languages English, Spanish, German,
French, Japanese, Chinese, Italian and Korean, plus two custom,
user defined languages can be uploaded into the instrument using
Master Software Tools, supplied with the instrument.
NEW
Fast Sweep Speed
The MS2721A can do a full span sweep in ≤900 milliseconds, and
sweep speed in zero span can be set from less than 50 microseconds up to over 4000 seconds. This is faster and more flexible than
any portable spectrum analyzer on the market today, simplifying the
capture of intermittent interference signals.
+43 dBm Maximum Safe Input Level
Because the MS2721A can survive an input signal of +43 dBm – 20
watts – without damage, you can rest assured that the MS2721A can
survive in even the toughest RF environments.
Spectrum Monitoring
A critical function of any spectrum analyzer is the ability to accurately view a portion of the RF and microwave spectrum. The MS2721A
performs this function admirably thanks to the wide frequency range
and excellent dynamic range. A built-in 64 MB compact flash memory module allows over 2000 traces to be stored. An external compact
flash socket allows additional compact flash memory to expand the
trace storage without limit.
Multiple Markers
Display up to six markers on screen, each with delta marker capability.
In addition you may select a marker table that simultaneously shows
the status of all markers. In the table you can see the frequency, and
amplitude measurement value for all markers along with delta frequency and delta amplitude. Each marker can have not only a measurement reference frequency but also a delta frequency and delta
amplitude, effectively giving you up to twelve markers if you need them!
Noise Markers
The capability to measure noise level in terms of dBm/Hz or
dBµV/Hz is a standard feature of the MS2721A.
Frequency Counter Markers
The MS2721A Spectrum Master has frequency counter markers with
resolution to 1 Hz. Tie this capability to an external precision time
base to get complementary accuracy and resolution.
Smart Measurements
The MS2721A has dedicated routines for smart measurements of
field strength, channel power, occupied bandwidth, Adjacent
Channel Power Ratio (ACPR) and C/I.
