1.1 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
●
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.
