FEATURES 2650
1 Compact and lightweight 3.75 lb (1.7 kg)
The dimensions are as small as WxHxD 6.4 x 2.75 x
10.25” (162 x 70 x 260 mm), and the weight is only
3.75 lb (1.7 kg) including the battery. It is very convenient
for outdoor use and while on business trips.
2 Measuring frequency range 50kHz to
3.3GHz
This bandwidth covers those of W-CDMA, CDMA, PDC,
PHS, GSM, 2.4GHz band wireless LAN,
Bluetooth.
3 Operation with battery for 100 minutes
When the battery is fully charged, Model 2650 operates
for about 100 minutes (with the back light turned off). It is
extremely convenient for outdoor use and for measuring
wireless LAN installation environment.
4 P
erformance that is compar
able to large-
siz
e bench type
Model 2650 guarantees a highly stable frequency axis by
PLL synthesizer system. The center frequency setting
resolution is 100kHz. Furthermore, the average noise
level of -110dBm (typical) provides a wide dynamic range
and the reference level can be set in 1 dB step.

LAN working environment.
● Magnetic field strength meas. ··· Optimum for EMI
design of PCBs and for evaluation of
signal quality.
6 Auto tuning
The center frequency is set at the spectrum of the
maximum level in the 3.3GHz 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 opera
tion
The resolution bandwidth, video bandwidth and sweep
time are automatically set based on the frequency span.
It is also possible to set auto range operation only one or
two out of resolution bandwidth, video bandwidth and
sweep time.
8 Har
d copy of the image
Connect a printer (PT 2650 optional) and press the
PRINT key on Model 2650. The image on the screen is
printed as it is.
9 High resolution display on the PC screen
The spectrum waveform is displayed at high resolution,
1000 points in the horizontal axis, on the PC screen when "PC
Software AK 2650" (optional) is used.
Model 2650 is a compact, lightweight, high performance spectrum analyzer that provides signal
analysis and functionality comparable to larger
bench type models.
Measuring functions 2650
Channel power measurement
Measures the sum of the power in
the zone specified by the zone
center and zone width (slash area
in figure). In short, it is possible to
measure the total power in the
specified frequency band. Of
course it is possible to measure
the noise power.
Adjacent channel power measurement
Capable of measuring the adjacent
channel power leakage as the ratio
of the power in the range specified
by offset frequency and bandwidth
(slash area in figure) to the carrier
wave power. Both the upper and
lower side power leakage are
measured.
Furthermore, the method for measurement may be selected out of three methods, i.e.,
total power method, reference level method and inband method, from the classification of definition of
carrier wave power.
Magnetic field strength measurement
Model 2650 is capable of precisely measuring the magnetic field
distribution on an LSI or a printed circuit board using magnetic
field probe PR 26M (optional)
As the magnetic field detection portion of PR 26M is of a shielded loop structure that adopts glass ceramic multi-layer board
technology of excellent high frequency characteristics, it is possible to take measurement at high reproducibility by detecting
magnetic field components only. The measuring frequency
range is as broad as 10MHz to 3GHz, and the measured value
is calibrated in the instrument.
Evaluation of effectiveness of the bypass capacitor located at
the power supply terminal of an LSI and evaluation of wiring rule
on a printed circuit board can be raised as typical use of PR
26M. PR 26M is not affected by adjacent patterns because of
high space resolution.
Occupied bandwidth measurement
It is possible to measure the
occupied frequency bandwidth
as the bandwidth of the point
that is lower by X (dB) than the
peak level or as the bandwidth
of the point of Y (%) of the total
power.
