3.1.2 SPAN

Set the span of the analyzer. The change of this parameter will affect the frequency parameters and restart the sweep.

Span

Set the frequency range of the current channel. Press this key to switch to center frequency/span input mode and the center frequency and span are displayed at the lower left and right sides of the grid respectively. Key Points:

• The start and stop frequencies vary with the span automatically.

• In manual span mode, the span can be set down to 100 Hz (the only way into the zero-span

mode is pressing the Zero Span menu option) and up to the full span described in

“Specifications”. When the span is set to the maximum, the analyzer enters full span mode.

• Modifying the span in non-zero span mode may cause an automatic change in both CF step

and RBW if they are in Auto mode, and the change of RBW may influence VBW (in Auto VBW mode).

• Variation in the span, RBW or VBW would cause a change in the sweep time.

• You can modify this parameter using the numeric keys, knob, or direction keys. For more details, please refer to “Parameter Setting”.

Full Span

Set the span of the analyzer to the maximum.

Zero Span

Set the span of the analyzer to 0 Hz. Both the start and stop frequencies will equal the center frequency and the horizontal axis will denote time. The analyzer measures the time domain characteristics of the amplitude of the corresponding frequency point on the input signal. Key Points: As opposed to the Non-zero span, the screen shows the time domain characteristics of the fixed frequency component in zero span mode.The following functions are invalid in Zero span mode:

“Zoom In” and “Zoom Out” in SPAN Zoom In

Set the span to half of its current value. At this point, the signal on the screen is zommed in on to observe signal details.

Zoom Out

Set the span to twice the current value. At this point, the signal on the screen is zoomed out on to gain more information about the signal.

3.1.3 AMPT

Set the amplitude parameters of the analyzer. Through modifying these parameters, signals under measurement can be displayed in a proper mode for easier obsercation and minimum error.

Ref Level

Set the maximum power or voltage can be currently displayed in the window and the value is displayed at the upper left corner of the screen grid. Key Points:

• The maximum reference level available is affected by the maximum mixing level, input attenuation and preamplifier. When you adjust it, the input attenuation is adjusted under a constant maximum mixing level in order to fulfill the following inequality:

Scale/Div

Set the logarithmic units per vertical grid division on the display. This function is only available when the scale type is set to “Log”. Key Points:

• By changing the scale, the amplitude range available is adjusted.

Scale Type

Set the scale type of Y-axis to Lin or Log, the default is Log. Key Points:

• In Log scale type: the Y-axis denotes the logarithmic coordinate, the value shown at the top of the grid is the reference level and each grid represents the scale value. The unit of Y-axis

will automatically switch to the default “dBm” in Log scale type when the scale type is

changed from Lin to Log.

• In Lin scale type: the Y-axis denotes the linear coordinate, the values shown at the top of the grid and the bottom of the grid are the reference level and 0 V respectively. Each grid represents 10% of the reference level and the Scale/Div is invalid. The unit of Y-axis will automatically switch to the default “Volts” in Lin scale type when the scale type is changed from Log to Lin.

• The scale type does not affect the unit of Y-axis.

Units

Chapter4 Test Case

 Testing Low Level Signal

 Testing Signal Distortion

4.1 Testing Low Level Signal

This section introduces how to test low level signal, and how to differentiate it with the noice in the same spectrum. The following is three methods to test low level signal.

4.1.1 Reduce the Loss of Input

The ability of spectrum analyzer to test low signal is limited by the noice produced

internally. The level is influenced by input attenuator when signal passes the

spectrum analyzer. If the signal is very close to the bottom of noise, it can differentiate

the signal with the noice to reduce the loss of input.

1) Reset spectrum analyzer

2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm. Connect

the RF OUT port of signal source to the RF IN port of spectrum analyzer and turn

on the signal output.

3) Set center frequency, span and reference level:

 Press FREQ  1GHz

 Press SPAN  5MHz

 Press AMPT - 40dBm

4) Move the peak value that needed to the center of screen.

 Press MARKER  Peak

1) Reduce the span to 1 MHz. If need, move the peak value to the center of screen

again.

 Press SPAN 1 MHz

2) Set the attenuation as 20 dB. Pay attention that when the attenuation increases,

the bottom of noice will be more close to signal level.

 Press AMPTAttenuation 20dB

3) Press AMPT Attenuation 0 dB, set the attenuation as 0 dB.

4.1.2 Reduce the Resolution Bandwidth

The internal noice level is influenced by resolution bandwidth, but continuous wave

signal is not. Decrease RBW into 10%, and the bottom noise will also decrease 10

dB.

1) Reset spectrum analyzer

2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm.

Connect the RF OUT port of signal source to the RF IN port of spectrum

analyzer and turn on the signal output.

3) Set center frequency, span and reference level:

 Press FREQ  1GHz

 Press SPAN  5MHz

 Press AMPT - 40dBm

4) Reduce resolution bandwidth.

 Press BW, and press manual. The resolution bandwidth can be reduced by

knobs and arrow key. Because the noise level reduces, the low level signal

will be clearer, as following picture.

4.1.3 Trace Average

Taking the average is the digital processing. It is to plus current value in each trace point and previous average value, and then take the average. Choose the operation of taking average. When spectrum analyzer is doing the automatic coupling, it can make the displayed noise level get smooth to change detection mode into sampling mode.

1) Reset spectrum analyzer

2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm.

Connect the RF OUT port of signal source to the RF IN port of spectrum

analyzer and turn on the signal output.

3) Set center frequency, span and reference level:

 Press FREQ  1GHz

 Press SPAN  5MHz

 Press AMPT - 40dBm

4) Press TRACE Average (ON) to turn on the average function.

 Press 100  ENTER, set the number of average as 100. Because the

operation of taking the average will make the trace be smooth, and the low level signal will be clearer.

4.2 Measuring Signal Distortion

This selection introduces how to recognize and measure signal distortion.

Recognize the distortion produced by spectrum analyzer.

The high level input signal may cause the distortion signal produced by spectrum

analyzer. This distortion signal will cover the true signal that needs to be measured in

the input signal. The user can recognize these signals through trace and RF

attenuator. If yes, this distortion is produced inside the instrument. In this case, we

use a signal output by a function generator as signal source to recognize whether the

harmonic distortion component is produced by spectrum analyzer.

1. Connect function generator to RF IN of spectrum analyzer. Set the input

frequency and amplitude of signal source as 200MHz, -10dBm.

2. Set center frequency and span of spectrum analyzer.

 Press [PRESET] (to restore factory settings) •  Press [FREQ]  400MHz •  Press [SPAN]  700MHz

The harmonic distortion component produced by this signal at the inputmixer of spectrum analyzer (arranged in turn with original 200MHz signal at 200MHz interval).

1. The center frequency should be changed as the frequency value at the first

harmonic wave.

 Press [MARKER]  PEAK

2. Change the span as 50 MHz, and display the signal in the center of screen again.

 Press [SPAN]  50MHz  Press [MARKER]  PEAK

3. Set the attenuation as 0 dB

 Press [AMPT]  Attenuation  0dB

4. To recognize whether the harmonic distortion component is produced by

spectrum analyzer, firstly display the input signal in trace 2



Press [TRACE]  Trace 2

 Press [TRACE]  Clear

5. Place a Delta mark in the harmonic distortion component of trace 2:

 Press [MARKER]  peak  Press [MARKER]  Delta

6. Press [AMPT]  Attenuation  10dB to turn up the RF attenuation to 10 dB.

The reading of amplitude difference is influenced by two factors:

1) To increase input attenuation will make signal to noise ratio (SNR) worse which will

cause the reading to be positive.

2) The loss of harmonic wave caused by internal circuit of spectrum analyzer will make the reading to be negative. To set the input attenuation can produce minimum reading.

5.1 SCPI Brief Introduction

SCPI (Standard Commands for Programmable Instrument) is an ASCII- based instrument command language designed for test and measurement instruments, with the goal of reducing automatic test equipment (ATE) program development time. SCPI accomplishes this goal by providing a consistent programming environment for instrument control and data usage. This consistent programming environment is achieved by the use of defined program messages, instrument responses, and data formats across all SCPI instruments. By providing a consistent programming environment, replacing one SCPI instrument with another SCPI instrument in a system should require less effort than with non- SCPI instrument. SCPI is not a standard which completely provides for interchangeable instrumentation. SCPI helps move toward interchangeability by defining instrument commands and responses, but not functionality, accuracy, resolution, and so forth.

5.1.1 Basic Knowledge Requirement

Programming with SCPI requires knowledge of:

• Computer programming languages, such as C or C++.

• The language of your instrument. A HAS Series spectrum analyzer employs SCPI as its

programming language.SCPI.

5.1.2 Command Syntax

Command syntax includes standard notations and statement rules. Command Statement Rules Overview

• Command statements read from left to right

• Use either long form or short form of keywords, but do not use both

• No separating space between the keywords, only use a colon to separate keywords of

different levels

• Always separating a keyword from a variable with a space

• Always separating a variable from its unit with a space (if variable has a unit)

5.1.3 Standard Notations

A command consists of mnemonics (keywords), parameters and punctuation. Before you start to program your analyzer, familiarize yourself with the standard notation of each of them.

Keywords

Many commands have both a long and a short form: use either one. (a combination of the two is not allowed). Consider the: FREQuency command for example:

• Short form : FREQ

• Long form : FREQuency

SCPI is not case sensitive, so fREquEncy is just as valid as FREQUENCY, but FREQ and FREQUENCY are the only valid forms of the FREQuency command. In this documentation, upper case letters indicate the short form of the keyword. The upper case and lower case letters indicate the long form of the keyword.

5.1.4 Punctuation

• A curly brackets “{ }” indicates a variable parameters to be defined.

• A vertical bar "|" dictates a choice of one element from a list. For example: <A>|<B> indicates

that either A or B can be selected, but not both.

• Square brackets "[ ]" indicates that the enclosed items are optional.

• Angle brackets "< >" indicates a variable value to be defined.

• A question mark "?" after a command indicates that this command is a query. The instrument

should return a data to the controller

5.1.5Separator

• A colon “:” separates keywords of different hiberarchy.

• A space separates a keyword and a parameter, as well as a parameter and a unit.

5.1.6 Default unit of parameters

The analyzer has the following default units for numeric variables.
