Products Line up

Features

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

5.7 inches, 640×480 dots and color LCD.

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 (SINGLE,DUAL,DELTA) 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, Portable antenna, Magnetic field probe, USB printer, Frequency counter, Lithium-ion battery and Test accessories are available.
