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 trips.
• Compact and lightweight 1.8kg
• Large and color TFT display5.7 inches, 640×480 dots, and color LCD
• Four hours battery operationLithium-ion battery MB400 (option) fully charged enables about four-hour battery operation at minimum backlight brightness.
• USB memoryUSB memory can be used as removable storage. The screen image is stored in BMP format, and the spectrum and setting parameters are stored in CSV format.
• USB communicationSuch fast transfer rate as 12Mbps maximum was achieved by the adoption of USB interface.
• Accurate frequency measurement by PLL synthesizerThe center frequency is accurately set by PLL (Phase Locked Loop) synthesizer. Moreover, the frequency counter (factory option) enables measuring the frequency of the signal more accurately.
• Average noise level -127dBmThe low average noise level of -127dBm @ 1GHz provides a wide dynamic range.
• 100dB display dynamic rangeAs the display scale on the amplitude axis is 100dB/10div (at 10dB/div), the signal is observed in a wide dynamic range.
• Easy operation by AUTO modeBy 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 the full span, and the optimum RBW, VBW, and sweep time are chosen.
• Competitive functionsMeasuring functions: Channel power, Adjacent channel power, Occupied bandwidth, Electric field strength, Magnetic field strength, and Frequency measurement.
  Calculation functions: Max hold, Min hold, Averaging, Overwrite Marker measurement, and peak search function.
• Save/Load function
• Hard copy with a printer
• Abundant optionsA 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
