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.

Span is to define the frequency range of measurement. When all the BW settings (RBW, VBW

and Sweep Time) are in

Auto mode, BW settings is changed following the change of the span.

Please refer to the BW function to see the details.

Full Span will set the Span at 2700MHz, in other words, the start frequency is at 0 and stop is at

2700MHz.

Zero Span will stop the frequency sweep and stay at the Center frequency. In other

words, the unit only measures the center frequency. When the tracking generator is in use, it will

generate a fixed frequency signal not sweeping signal. Refer to

TG (Option→TG) function for

details.

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.

Reference Level is the top level on the display. The level of input signal is recommended to

be under the reference level to have accurate result.

The

Scale can be switched in 10-5-2-1 dB sequence. Note that the accuracy will not change

following the scale change. It is a graphical Zoom in function.

Unit includes dBm, dBuV, dBmv and dBm/Hz. There is a transformation factor 107 between

dBm and dBuV.under 50Ω system, and 47dB factor between dBm and dBmV. The dBm/Hz is the so-called noisy marker which normalizes the reading into 1Hz bandwidth.

ExtGain/Loss allows the amplitude offset caused by user’s application.

InputZ can toggle the input impedance between 50Ω and 75Ω. Note the 50Ω and 75Ω

switch here is a software adjustment.

Input Z Cal offers the compensation entry of the 75Ω

adaptor. The ideal number is at 5.9dB

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.

Center Frequency. It

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.
