Excellent Basic Performance
High C/N ratio to securely capture
adjacent signals
The MS2687B has excellent noise sideband
characteristics of –108 dBc/Hz or lower (1 GHz, 10 kHz
offset), which is ideal for analyzing weak signals adjacent
to strong signals or a narrow bandwidth carrier.
Broad dynamic range that accurately
captures weak signals
With the development of digital radio technology, analyzed
signals are becoming weaker and broader than ever. With
the MS2687B, a dynamic range display of up to 156 dB
(typical value) has been achieved, thus allowing accurate
analysis of even weak signals.
The resolution bandwidth of up to 20 MHz permits the
analysis of broadband signals and can handle the broader
bandwidths of the future.
Extremely low distortion rate suitable
for power amplification or harmonic
measurement
The MS2687B has extremely low harmonic distortion
levels, including second harmonic distortion of –90 dBc
and two-signal third-order distortion of –85 dBc, making it
suitable for evaluating the non-linearity of high-power
amplifiers and for measuring harmonics.
Instantaneous evaluation of various
radio devices
Standard measure functions
The MS2687B has a wealth of measuring functions to
perform various high-speed evaluations of radio devices
such as power measurement, frequency measurement,
adjacent channel leakage power measurement, and mask
measurement.
Optional measurement software is also available for
instantaneously analyzing various digital communication
systems by just installing the software.
