Features of MSA400 Series

• The dimensions are as small as 162(W)×71(H)×265(D)mm, and the weight is only 1.8kg including the battery. It is very convenient for outdoor use and on business trip.
• Compact and lightweight 1.8kg
• Large and color TFT display

  5.7 inches, 640×480 dots and color LCD

• Four hours battery operation

  Lithium-ion battery MB400 (option) fully charged enables about four-hour battery operation at minimum backlight brightness.

• USB memory

  USB memory can be used as a removable storage. The screen image is stored by BMP format, and the spectrum and the setting parametersare stored by CSV format.

• USB communication

  Such fast transfer rate as 12Mbps maximum was achieved by adoption of USB interface.

• Accurate frequency measurement by PLL synthesizer

  The center frequency is accurately set by PLL (Phase Locked Loop) synthesizer. Moreover, the frequency counter (factory option) enables to measure the frequency of the signal more accurately.

• Average noise level -127dBm

  The low average noise level of -127dBm @ 1GHz provides a wide dynamic range.

• 100dB display dynamic range

  As the display scale in the amplitude axis is 100dB/10div (at 10dB/div), the signal is observed in a wide dynamic range.

• Easy operation by AUTO mode

  By auto range operation, RBW, VBW and sweep time are automatically selected based on the frequency span. By auto tuning operation, the center frequency is adjusted to the maximum level within full span, and the optimum RBW, VBW and sweep time are chosen.

• Competitive functions

  Measuring functions : Channel power, Adjacent channel power, Occupied bandwidth, Electric field strength, Magnetic field strength and Frequency measurement.
  Calculation functions : Max hold, Min hold, Averaging, Over write Marker measurement and peak search function

• Save/Load function
• Hard copy with printer
• Abundant options

  A lot of options such as PC software, Logging software, VSWR bridge, Dipole antenna, Magnetic field probe, USB printer, Frequency counter, Lithium-ion battery and Test accessories are available.

Channel power measurement

The sum of power in the band specified by band center
and band width (colored area) is measured.In short, it is
possible to measure the total power in the specified frequency
band. Of course, this function enables to measure a noise power

The conventional method covering the wide band with a single antenna results
in low antenna gain because of using the range away from an antenna
resonance point, and the dynamic range extremely worsens as a result. To use
a resonance point where the antenna gain is high, six kinds of antennas are
provided according to the frequency bands. Therefore, each antenna secures
a wide dynamic range. Antennas of other bands will be also provided if
requested.
Since the electric field strength is calibrated for each antenna in MSA400
series, it is possible to directly read the measured value.
Moreover, the electric field strength
is also measured with an user’s
antenna besides antennas from
M401 to M406 if “USER” antenna
is selected.

Magnetic field strength measurement

MSA400 series measures precisely
the magnetic field distribution on
LSI or PCB using the magnetic
field probe CP-2S (option). As the
magnetic field detection portion
of CP-2S is of a shielded loop
structure using a glass ceramic
multi-layer board technology with
excellent high frequency characteristics, it enables the measurement with high
reproducibility by detecting magnetic field components only. The measuring
frequency range is as broad as 10MHz to 3GHz, and the measured value is
calibrated in the instrument

The typical applications of CP-2S are the evaluation of effectiveness of a
bypass capacitor located at a power supply terminal of LSI and the evaluation
of wiring rule of PCB. CP-2S is not affected by adjacent patterns because of
high space resolution
