There are two methods to set the measuring frequency, Center/Span and Start/Stop. Span
means the measuring bandwidth. Center and Span are usually used in the situation that the
frequency under test is known. Start and Stop are used for the measured frequency of a specific
range.
Step and Peak to Center are functions to make easy operation in some case. When the step is
defined, the frequency entry will change for the step number. Peak to Center will find the peak
signal on display and then change the center frequency to the frequency of peak signal. Peak to
Center will not activate the marker.

When Zero Span is performed, the measuring frequency will stop sweeping, and only fixes on
Center frequency. An example of AM (amplitude modulation) signal is described above. The
modulating signal is at 100Hz sine wave. Since the measuring frequency is fixed, the display
will present the amplitude variation of AM signal, which is at 100Hz in this case.

There are two operation modes of Markers due to Marker Number in operation. In single
Marker mode,
Marker is used to read the frequency and level readings of signal on the
display.
This unit offers two modes of marker operation, single marker and multi-marker modes. In
single marker mode, the
signal.
Marker to Center function will change the Center frequency to the marked
frequency by marker.
To Peak function will let the marker find and stand on the peak
Delta (∆) mode will activate the delta marker, which will present both
the frequency and level differences with the reference marker.
The
Multi-Marker mode can activate more markers up to ten. Under multi-marker mode,
the measurement readings are displayed on the marker table. Every marker can be specified
to be ∆Marker, and specify any other marker as its reference marker.
Markers to Peaks
function allows the markers to find the peak signals automatically. It is very useful to pick
the EMI signals.

Track function will dynamically track the Peak signal and move the signal to the center. In fact,
it equal to the combination of
Peak Search + Marker to Center which is performed all the
time.
Note: Because the marker continuously keeps searching the peak signal and moving it to the
center on the display, therefore the Center Frequency is changeable as long as the track
function is on.

There are three traces
Live, Tr. A and Tr. B. Live trace is always the one measuring the
signal. Trace A and Trace B are the traces for memory access. The Clear function is to clear the
Trace A and Trace B.
Live Trace has
Peak Hold, Average and Freeze functions. Peak hold function is to hold the
peak signal until the next higher level signal is appeared. When the next higher signal is coming,
it will update the signal. Average function will average the specific number of traces and
present the result of average on the display. Freeze function will stop sweeping and present the
last trace.
The
Trace Math directly uses the trace data to perform the math operation. In other words,
when trace A plus trace B in dB, the result is dB number pulsing other than transferring into
linear scale.
There are also several detection modes are provided. Basically the data of every point is
taken from several samples. How many samples are taken for one data will depend on the
setting of
RBW and SPAN. There are several ways to pick one to present the all taken samples.
Normal mode takes average, Sample mode will pick randomly, and Peak + mode will pick the
maximum one. It is so-called positive peak sometimes.
There are also two detection modes implemented by hardware.
filter. There are three time constants of
Quasi Peak detection, TC1, TC2 and TC3 for 600ms,
Average is done by low pass
550ms and 160ms respectively.

Power measurement functions provide the
ACPR (Adjacent Channel Power Ratio),
OCBW (OCcupied BandWidth). For ACPR measurement, the CH BW (channel
bandwidth),
Adj CH SPC (adjacent channel bandwidth) and Adj CH Offs (adjacent
channel offset) have to be specified first. The ACPR measurement turns out the power
ratio of main channel and upper/lower adjacent channels in dB. The terminology ACLR
(Adjacent Channel Leakage Ratio) is sometimes used instead.
Adj CH BW and Adj CH Offs are defined in ADJ CH OFFSET functions. Two types
of
ACPR with different channel BW and offset can be measured simultaneously. They are
noted as
Adj CH 1 (LACPR 1/ UACPR1) and Adj CH 2 (LACPR 2/ UACPR 2) in the
P0wer measurement table.

Trigger is the feature that the measurement starts when the trigger condition is met. In other
words, even in the trigger mode, the measurement sweep will not start until the trigger
condition is match. There are two trigger modes,
trigger condition is met, the
Single mode only performs one measurement sweep while the
Single and Continuous. As long as the
Continuous mode performs the sweep continuously. Before the trigger condition is met, the
sweep will not work.
There are two sources of trigger condition,
Video Level and External trigger from rear
panel. Video Level means the level of display. The input signal has to reach the video level
to trigger the measurement sweep. The default of trigger frequency is
can be changed with
Trigger Freq setting.

Another source of trigger is from
External Input on the rear panel. A 0 to 5V rising edge
will trigger the sweep in external trigger mode.
Trigger delay allows sweep happens later than the condition is match.

Option function is to control the function of TG, Demodulator, Extern Reference Frequency
and Battery.
TG, Tracking Generator can be switched ON/OFF and its Output Level is controlled by TG
function keys.
Offset offers a frequency offset between TG output and input frequency of
spectrum analyzer. It is programmable from -990kHz to 990kHz. When the offset is at
100kHz, it means the TG output frequency is 100kHz greater than spectrum analyzer.
Considering the flatness calibration of TG measurement, the
Normalization is to make the
through response flat. Therefore if the frequency response test is about to performe, directly
connect the TG output and RF input with the same testing fixture to normalize first, then
connect the DUT into test. The normalization will calibrate the uneven characteristics of
fixtures used. The
Ref Value allows that the normalized line of through response can be
specified at any level.
There are AM and FM in the
Demodulator option. The related control like Tone and
Squelch are also provided. The External Reference Frequency allows 13 selections that
depend on user’s application. The most common frequency 10MHz is surely included. When
the
Battery Pack is installed, activating the Battery monitor will give the information of
battery status.
