功能 | | ① | 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. | | | | ② | Large and color TFT display | | | 5.7 inches, 640×480 dots and color LCD | | | | ③ | Four hours battery operation | | | Lithium-ion battery enables about four-hour battery operation. | | | | ④ | 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. | | | | ⑤ | USB communication | | | Such fast transfer rate as 12Mbps maximum was achieved by adoption of USB interface. | | | | ⑥ | 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. | | | | ⑦ | Average noise level-127dBm | | | The low average noise level of -127dBm @1GHz provides a wide dynamic range. | | | | ⑧ | 100dB display dynamic range | | | As the display scale in the amplitude axis is 100dB/10div, the signal is observed in a wide dynamic range. | | | | ⑨ | 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. |
| | | | ⑩ | 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 |
| | | | | | | | | | ＆#9322; | 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. | | | | |
