Product outlines

The 2650A series are authentic spectrum analyzers in a compact and lightweight form factor providing

performance and functions comparable to large-size bench type instruments.

The features are as follows.

1) Compact and lightweight 1.8 kg.

The dimensions are 162(W)×71(H)×265(D) mm, and the weight is only 1.8 kg including the battery, making the

instrument very convenient for field use.

2) Large color TFT display

5.7 inches, 640×480 color LCD

3) Four hours battery operation

The included Lithium-ion battery, when fully charged, can provide power for up to four hours of operation with the

backlight turned off. And about 3 ½ hours with the backlight set to the minimum level.

4) USB host adapter

USB host port can be used with removable storage USB flash drives. The screen image is stored as BMP format, and

the spectrum and the setting parameters are stored as CSV format. The port conforms to USB 1.1 standards and is

backwards compatible with USB 2.0 devices.

5) USB device for PC connectivity

USB interface with transfer rates up to 12 Mbps maximum (conform to USB 1.1 standards).

6) 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 more accurate measurements of the frequency of a signal.

7) Average noise level -127 dBm

The low average noise level of -127 dBm @ 1 GHz provides a wide dynamic range.

8) 100 dB display dynamic range

Wide dynamic range display with a display scale of 100 dB/10div (at 10 dB/div) in the amplitude axis.

9) Easy operation with AUTO mode

● Autorange operation: RBW, VBW andsweep time are automaticallyselectedbasedonthe frequencyspan.

● Autotuningoperation: The center frequencyis adjusted tothemaximum level within full span, andthe optimum

RBW, VBW and sweep time are chosen.
