Caution
The input of the EMC analyzer can be damaged easily.When
using aline impedance stabilization network (LISN) device with
the EMC analyzer, disconnect the analyzer from the LISN device
before changing either the switch position on, or the voltage to,
the LISN device.

Getting Acquainted with the EMC
Analyzer
This chapter provides an introduction to the EMC analyzer's front-panel
features, an explanation of screen annotation, the procedure for making a
basic measurement with the EMC analyzer, and the procedure for performing
self-calibration routines. The EMC analyzer also supplies a spectrum analyzer
operating mode with screen annotation described in \Spectrum Analyzer Mode
Screen Annotation
"at the end of this chapter
.
Front-Panel Features
The following section provides a brief description of front-panel features.
Refer to Figure 1-1.

anel Display
is the area on the front-panel where information is
provided to the user
.That information includes:
A
ctive Function Block area. Functions appearing in this block include,
for example, marker, span, center frequency, and reference level.
Message Block area. This block is where MEAS UNCAL and the asterisk
(*) appear. If one or more functions are manually set (uncoupled), and
the amplitude or frequency becomes uncalibrated, MEAS UNCAL appears.
(Press 4
AUTO COUPLE
5 , then
NNNNNNNNNNNNNNNNNNNNNNNNNN
AUTO ALL , to recouple functions.) The
asterisk indicates that the display is not updated for new settings.
Softkey labels. Softkey labels are the annotation on the screen next to
the unlabeled keys. Most of the labeled keys on the EMC analyzer's
front panel (also called front-panel keys) access menus of related
softkeys.
2 Softkeys are the unlabeled keys next to the screen.

make manual or automated quasi-peak average measurements, adjust the
IF bandwidth, adjust the sweep time, store and manipulate trace data,
demodulate signals, control the markers, control the instrument display,

10 INPUT 50 is the signal input for the analyzer.
Caution
Excessive signal input will damage the EMC analyzer input
attenuator and the input mixer
.The maximum power that the
EMC analyzer can tolerate appears on the front panel.

13 VOL-INTEN changes the brightness of the screen display, and the volume
of the speaker.

EMC Analyzer Screen Annotation
Figure 1-2 shows an example of screen annotation as it appears on the screen of
the EMC analyzer
.T
able 1-1 lists the screen annotation features numerically and
refers to Figure 1-2.
Figure 1-2. EMC Analyzer Screen Annotation
In Figure 1-2, item number 19 refers to the trigger and sweep modes of the EMC
analyzer. The rst letter (\F") indicates the EMC analyzer is in free-run trigger
mode. The second letter (\S") indicates the EMC analyzer is in single-sweep
mode. (\C") indicates the EMC analyzer is in continuous-sweep mode.
Item number 20 refers to the trace modes of the EMC analyzer. The rst letter
(\W") indicates the EMC analyzer is in clear-write mode
. The second letter (\A")
represents trace A. The next two letters (\SB") indicate the store-blank mode
(\S") for trace B (\B"). The trace mode annotation for trace C is displayed under
1-4 Getting Acquainted with the EMC Analyzer

the trace mode annotation of trace A. In Figure 1-2, the trace C trace mode is
\SC," indicating trace C (\C") is in the store-blank mode (\S").
The WINDOWS display mode splits the screen into two separate displays.Only
one of these displays is active at a time. The currently active window will
have a solid line around the graticule rather than a broken line. The complete
annotation is not available for each window because of space limitations.

Making aBasic Measurement
Basic measurements simply involve tuning the instrument to place a signal on
the screen, then placing amarker on one or more signals, measuring those
signals
,and moving those signals to a list.
Caution
Do not exceed the maximum input power that is printed on the
front panel of the EMC analyzer.
Let's begin using the EMC analyzer by measuring an input signal. Since the
300 MHz calibration signal (CAL OUT) is readily available, we will use it as our
input signal.

EMC ANALYZER and proceed with the next step.
3. Connect CAL OUT to the EMC analyzer INPUT 50 connector (on the front
panel) using an appropriate BNC cable and a BNC-to-Type N adapter.
Option 026 only: Connect the SMA (m) to SMA (m) cable to the EMC
analyzer input with an APC-3.5 connector. Connect the cable to CAL OUT
with the BNC-to-SMA adapter.
4. Press 4
