Compact and lightweight 1.8kg

The dimensions are as small as 162(W)×70(H)×260(D)mm, and the weight is only 1.8kg including the battery.
It is very convenient for outdoor use and on business trip.

150 minutes battery operation

Ni-MH battery MB300 (option) fully charged enables about 150 minutes battery operation at backlight-off.

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 -117dBm

The low average noise level of -117dBm@1GHz provides a wide dynamic range.

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

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.

Measuring electric field strength from 300MHz to 6.2GHz

The band is covered with the seven kinds of portable antennas. According to an application, one of them is chosen.
