™ continuous carrier
power level measurement is still
available. By ‘slicing’ the desired
channel and measuring across the
entire spectrum, tilt, spectrum
shaping, and other problems are all
detected accurately.
With these capabilities, the
SAM 4040D offers the most com-
prehensive digital measurement
package in any SLM.
The Same Tough Stealth Package
All of these new features are in
the same package that propelled
the current 4040 Signal Analysis
Meter, and other Stealth instru-
ments, to become the industry
leader in field maintenance and
sweep test.
• Lightweight– At 4.9 lbs., the
SAM 4040D is half the
weight of most competitors.
• Easy-to-carry– The SAM
4040D’s weight and size mean
it can be held in one-hand and
easily carried. You may not even
want to use the shoulderstrap.
• Water resistant– The SAM
4040D is ready for field use
no matter what the weather
conditions.
• High resolution display– The
320x240 dot matrix LCD pro-
vides high-resolution displays
of all measurements.
• Easy-to-use– The SAM 4040D
provides a simple user inter-
face that is now common on
all Wavetek’s SLM, leakage,
SAM and sweep meters. This
means less training time and
more time for troubleshooting.
Comprehensive Spectrum
Analyzer Display
Five times faster than the orig-
inal SAM 4040, when you press
SPECT, the spectrum update is as
fast as 750 ms per sweep. You can
zoom in and out with rapid button
presses to isolate ingress problems
or view TDMA signals.
More important is the ability to
catch transients and noise. The
SAM 4040D detects signals as fast
as 5 µs—in both zero span, and con-
tinuous modes. A built-in preamp
and 50 MHz low-pass filter allow
you to track down smaller signals,
even through high-loss test points.
The SAM 4040D’s expanded
SPECTRUM mode provides the
tools needed to find ‘difficult’
problems.
• Programmable ‘dwell’ time
allows the meter to stay on
each frequency longer and
catch more ingress.
• Peak hold in spectrum mode
saves transient spikes instead
of overwriting them with the
next trace.
• CSO/CTB mode for automat-
ically making intermodulation
measurements.
Wavetek’s New
Zero-Span Display
While tracking down ingress, a
spectrum Zero-span mode allows
the user to ‘camp’ on a given fre-
quency and see a signal as it
comes and goes.
The SAM 4040D also measures
and analyzes digital TDMA chan-
nels. First, you can observe the
power level of a packet/message.
Move the cursor onto the packet,
and the SAM 4040D indicates the
level. In addition, desired/unde-
sired levels are displayed in real
time. Moving the cursor to an
empty time slot produces an auto-
matic desired/undesired (carrier to
noise) measurement. Adjustable
resolution and video bandwidths
can be used to tailor zero-span dis-
plays to show what the user wants.
Adjustable measurement band-
width automatically calculates full
channel power in zero-span mode.
Sample Spectrum Display
Zero span mode provides accurate TDMA mea-
surements.
SAM 4040D's new Navigator screen makes find-
ing measurement modes easy.
