1.1 Product outlines 2650/2652/2658
2650/2652/2658 is an authentic spectrum analyzer providing performance and functions that are
comparable to those of large-size bench type equipment, in a compact, lightweight and inexpensive
model.
1) Compact and lightweight, 1.8 kg(2650/2652/2658)
The external dimensions are as small as (W×H×D) 6.4×2.8×10.2” (162×70×260mm), and the weight is
only 3.7lb(1.8 kg) including the battery. It is very convenient for outdoor use and while on business trips.
2)Measuring frequency bandwidth 50kHz to 3.3GHz(2650/2652)/50kHz to 8.5GHz(2658)
This bandwidth covers those of W-CDMA, CDMA, PDC, PHS, GSM, wireless LAN, Bluetooth, etc.
3) Operation with battery for 110 minutes
When battery BP 2650 is fully charged, 2650/2652/2658 works for about 110 minutes (with the back
light turned off). It is extremely convenient for outdoor use and for use in the survey of wireless LAN
installation environment.
4) Performance that is comparable to that of large-size bench type equipment
2650/2652/2658 guarantees a highly stable frequency axis by PLL synthesizer system. The center
frequency setup resolution is 100kHz. Furthermore, the mean noise level is -110dBm or less. Thus,
a broad dynamic range is secured and the reference level can be set in 1 dB steps.
5) Abundant functions
·
Measuring functions··· Channel power measurement, Adjacent channel leakage power measurement,
Occupied frequency bandwidth measurement, Electric field strength
measurement, Magnetic field strength measurement (optional), Frequency
counter (factory option)．
· Electric field strength measurement: Optimum for measurement of cellular phone and
wireless LAN working environment.
· Magnetic field strength measurement: Optimum for EMI design of printed circuit boards
and for evaluation of signal quality.
· Calculation functions··· MAX HOLD, MIN HOLD, AVERAGE, OVER WRITE
· Marker & peak search · Save/load
6) Auto tuning
The center frequency is set at the spectrum of the maximum level in the 3.3GHz(2650/2652)
/8.5GHz(2658) band, and in addition, optimum reference level, resolution bandwidth, video bandwidth
and sweep time are set when the AUTO TUNE key is pressed. This function is very convenient for
measurement of an unknown signal.
7) Auto range motion
The resolution bandwidth, video bandwidth and sweep time are set automatically based on the set
frequency span. It is also possible to set auto range motion only one out of resolution bandwidth,
video bandwidth and sweep time.
8) Hard copy of the image
Connect a printer (optional) and press the [PRINT] key on 2650/2652/2658. The image on the screen is
printed as it is.
