Informazioni:
                                    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 (WxHxD)
6.4x2.8x10.2” (162x70x260mm), 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.
9) High resolution display on the PC screen
The trace is displayed at high resolution, 1001 points in
the horizontal axis, on the PC screen when “PC Software AK
2650” (optional) is used.
