Compact and Powerful

Synthesized local oscillator

The synthesized local oscillator design permits stable mea­surements without disturbance due to frequency drift of the
spectrum analyzer itself. The level stabilizes in 30 minutes
after power-on, making this unit especially suitable for on-site
maintenance and adjustment where work must be completed
quickly.

Counter with 1 Hz resolution

A full complement of frequency counter functions are provid­ed. Resolution is as high as ±1 Hz even at full span, and high­speed frequency measurements can be performed. The high
sensitivity compared with ordinary counters makes it easy to
select one signal from many and to determine its frequency.

Highly-accurate measurement

Automatic calibration ensures a high level accuracy. A span
accuracy of 5% and 501 sampling points ensure accurate
occupied frequency bandwidth and adjacent channel power
measurements.

Occupied bandwidth measurement

Excellent cost vs performance

The superior basic performance, including noise sideband,
average noise level, and spurious response, provides excel­lent cost vs performance.

adjacent channel power measurements, MS2667C can

Convenient, Easy-to-Use Functions

Simple operation

Users require ease of operation in a wide variety of contexts.
The front panel, key layout and softkey menu were simplified
for ease-of-use. Also, “page-learning” and “user-defined” func­tions have been added to minimize the steps required for a
given procedure.

Bright color screen

A 5.5” bright color TFT-LCD is used to custom configure the
display scales, measured waveform data, settings and other
parameters for easy viewing. Each color can be changed inde­pendently. When the soft key display is turned off, the scale
area enlarges to 80 (H) ✕ 180 (W) mm, comparable to an 8”
CRT.

Radio equipment evaluation
functions(“measure” functions)

A full range of functions including measurement of power lev­els, frequencies, adjacent channel power, and mask and time
template measurements are provided for performance evalua­tion of radio equipment. Key operation is simple and high­speed calculations make the measurement fast and efficient.

Convenient Easy-to-Use Functions

FM-demodulated waveform
display function

This function displays FM-demodulated waveforms with an
accuracy of 5% over the range ±10 kHz to ±1 MHz. When
used with high-speed time domain sweep (Option 04) and trig­ger/gate circuit (Option 06), frequency deviation of the modu­lated signal, as well as frequency switching times of radio
equipment and VCOs, can be measured.

Spectrum and FM-demodulation waveform

Zone sweep and multi-zone
sweep functions

Sweeps can be limited to zones defined by zone markers
which results in reduced sweep time. This zone sweep func­tion can be combined with “measure” functions such as “noise
measure” which can direct readout the total noise power within
the zone to reduce measurement time greatly. The multi-zone
sweep function enables up to ten zones to be swept.

Multi-zone sweep

Zone markers and multimarkers

Zone markers can be set automatically at the peak signal with­in a given marker range, enabling quick measurement. By
using the multimarker function, automatic measurements can
be performed at up to ten markers, with the results displayed
in a table. With the multimarker function, up to 10 harmonics
of the carrier can be measured, as well as the 10 highest spu­rious levels within the frequency span. Also, up to 10 markers
can be manually set for automatic frequency and amplitude
measurements.

Multimarker (highest 10 points) Multimarker (harmonics measurement)

Multi-screen display

Screen image bitmap saved to

The Trace A and Trace B waveforms are superimposed on the
same screen, and two spectra with different frequencies are
displayed simultaneously. In addition, it is possible to simulta­neously display spectrum and time domain screens for the
same signal. The multi-screen display permits efficient signal
level adjustment and harmonic distortion measurement, too.
Furthermore, in addition to being able to display amplitude in
the time domain, it is also possible to display the FM demodu­lation waveform.

Two traces with different frequencies

memory card

Instead of printing a hard copy of the screen, it is also possible
to save the screen image to a memory card in bitmap format.
Editing the saved bitmap data using a PC, makes report writ­ing easy.

When the mode to save the screen
image in bitmap format to the memo­ry card is selected as a copy method
at the hard copy function, just one

▼

press of the copy key saves the
screen image as a bitmap format to
the memory card. And the file num­ber of each saved file is incremented
automatically.

The screen image data can also be

▼

saved to the memory card using the
save function. In this case, the file
number of the saved file can be spec­ified.

User-defined functions

operation. Other panel and function keys can also be prede­fined in the same way.

Versatile Options

The enhanced performance and digital functions of recent radio equipment necessitate measuring equipment with even more
sophisticated functions and performance. Versatile options are available to meet such needs.

To boost basic performance

Narrow resolution bandwidth (Option 02/03)

The frequency resolution is improved by adding an optional
narrow resolution bandwidth filter. Option 02 (30, 100, and 300
Hz) and 03 (10, 30, 100, 300 Hz) are provided. In Option 03,
average noise level at RBW 10 Hz is specified.

For testing digital mobile
communication equipment

High-speed time domain sweep (Option 04)

Testing of TDMA-type radio equipment includes time domain
(zero-span) measurements of antenna power, transient
response characteristics of burst transmissions, transmission
timing, and other quantities. The high-speed time domain
sweep option boosts a sweep time to 12.5 µs and resolution to

0.025 µs. ∗This option must be used with the trigger/gate cir­cuit (Option 06).

Trigger/gate circuit (Option 06)

The trigger function provides stable measurements of burst
signals in the time domain. External, video, wide IF video, or
line trigger can be selected.
PASS/FAIL measurements are easily made on TDMA radio
burst signals using limit lines created in the template function.
Pre-trigger and post trigger delays can be used. Burst signals
can also be measured in the frequency domain using the gate
sweep function. A wide IF video trigger function is used,
eliminating the need for an external trigger source that was
previously required.
