°@The best-seller model MSA300 series was extremely upgraded to MSA400 series as shown in
°@"Comparison between MSA300 and MSA400 series" table. However, the weight and dimensions
°@are almost same, and the price was suppressed as low as possible.

Compact and lightweight 1.8kg
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.
Large and color TFT display

Four hours battery operation
Lithium-ion battery enables about four-hour battery operation.°@
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 parameters are stored by CSV format.°@
USB communication
Such fast transfer rate as 12Mbps maximum was achieved by adoption of USB interface.°@°@°@°@°@°@°@°@°@°@°@°@
Accrate 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, the signal is observed in a wide dynamic range.°@
Easy operation by AUTO mode
Auto range operation : RBW, VBW and sweep time are automatically selected based on the frequency span.
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.
