Making a Basic Measurement
Making a basic measurement with the Anritsu Spectrum Master is similar to making a mea-
surement with a conventional spectrum analyzer. Users need simply to power-on and tune
the Anritsu Handheld Spectrum Analyzer to locate and display a signal on the screen. Once
a signal is displayed, the user can measure the signal input in four simple steps to determine
the frequency and amplitude of the signal.
These steps are:
Setting the center frequency
l
Setting the frequency span
l
Setting the amplitude
l
Activating the marker
l
NOTE: Frequency, span and amplitude are the fundamental functions for spec-
trum analyzer measurements. However, by using marker functions, you are
able to read out frequencies and amplitudes on the spectrum analyzer trace.
This lets you make relative measurements, automatically locate the signal of
the highest amplitude on a trace, and tune the spectrum analyzer to track a sig-
nal. For more information, refer to Chapter 4, "Measurement Fundamentals."
Example – Measuring a 900 MHz signal
NOTE: A "reset" step is recommended to return the instrument to the factory
default settings if a known starting state is desired before beginning any mea-
surement. Some of the factory defaults include preamp off, RBW, VBW, and
Span automatically coupled, and attenuation coupled to the reference level.
There are two methods that can be used to reset the MS2711D to the factory
defaults:
If the unit is off, hold down the ESCAPE/CLEAR key while pressing the
ON/OFF key. This resets the instrument to the factory preset state for all
modes.
If the unit is on, press the RECALL SETUP key on the keypad. When the key is
pressed, a Recall Setup selection box for the current mode of operation ap-
pears on the display. Select setup location 0 <Default> to recall the factory pre-
set state for the currently selected mode.
Step 1. Press the ON/OFF key, then the ENTER key when prompted.
Step 2. Connect a signal generator to the input of the Anritsu Spectrum Master and con-
figure it to provide a -10 dBm, 900 MHz signal.
