with the VSA6G2A’s
trigger input it is
straightforward to view
these waveforms.
The analyzer’s
operation is divided
into two bands to cover
the complete operating
range: a low band (100
Hz to 2 MHz) and a
high band (1 MHz to
6. 2 GHz). The
VSA6G2A offers an N
(female) RF signal input connector
and a mini-B USB connector for
interfacing with the PC. Four MMCX
connectors provide I/Q port access.
Signal spectra are clearly
displayed on the attached PC, as well
as density, waterfall images, and
demodulated waveforms and eye
diagrams. The waterfall display helps
in showing signals like frequency
hopping Bluetooth. The VSA channel
power function makes it simple to
measure signal power automatically.
Production testing is also facilitated
when using preselected Pass/Fail
criteria.
Weighing only 3. 5 oz and
powered from a PC’s USB port, the
VSA6G2A is ideal for field test and
installation since it can be easily
slipped into a laptop bag and used
for monitoring RF signals in
temperatures from - 10°C to + 50°C.
It’s also suitable for use in benchtop
EMC testing with near-field antennas.

REAL TIME
SPECTRUM
ANALYZERS
Saelig also announces the availability of the Rigol
Technologies RSA5000 series of RF
spectrum analyzers. These real time
devices scan a complete frequency
spectrum of 9 kHz to 3. 2 or 6. 5 GHz
with a maximum sample rate of 51. 2
MS/s. They offer significant
performance improvements over
traditional swept spectrum analyzers
with a 1 ms full span sweep, an
expanded vertical range to + 30 dBm,
reduced phase noise to -108 dBc/Hz,
1 Hz RBW (resolution bandwidth),
and a reduced noise floor (DANL) to
-165 dBm. They can also be used in a
traditional swept scan mode.
Offering up to 40 MHz real time
bandwidth, the RSA5000 series
calculate >146,000 FFTs/sec,
delivering down to 7. 45 µs for a
100% probability of intercept.
There are seven display modes
(Normal, Density, Spectogram, Power
v. Time, Density & Spectogram, PVT
& Spectrum, and PVT &
Spectrogram) and a frequency mask
trigger is included; this is especially
useful for triggering measurements of
sporadic or transient events.
The flexible User Interface allows
customers a choice for interacting
with the units since they feature a
10.1” capacitive touch screen display
with gesture support, mouse/
keyboard support, as well as
traditional knob and button control.
Tracking Generator versions are
also available that add a built-in signal
source of 100 kHz– 3.2/6.5 GHz with
an output range of - 40 dBm to 0
dBm for plotting circuit or
component frequency responses.
The RSA5000 series of analyzers
offer a combination of swept
spectrum performance and 40 Hz
real time bandwidth, with category
leading 7. 45 µs POI, making the
RSA5000 a great choice for
customers in spectrum monitoring,
transmitter testing, RF component
characterization, and EMI
applications.
Customers working with
hopping/channel shifting
technologies in crowded ISM bands
will find a real time analyzer
essential, as will customers
integrating PLL technology in their
designs, identifying sources of
