SOFTWARE INSTALLATION
Before running SpectrumShot, first install the NI-488.2 software. You can download theNI-488.2 software from the National Instruments website.
Please Visit: http://www.ni.com
GSP-9330 spectrum analyzer users can download SpectrumShot from the official GWInstek
website.
Please Visit: http://www.gwinstek.com/en/index.aspx
SpectrumShot allows you to use simple mouse-controlled tools to work with the GSP-9330
Spectrum Analyzer.
The software can be run with any PC using Windows 8(32/64 bit), Windows 7 (32/64 bit), Vistaor XP operating systems.
To install SpectrumShot, select the spectrumshotsetup.msi file. The Setup Wizard will guide
you through the installation process.

4Remote Control Interface Setting

REMOTE CONTROL INTERFACESETTING
GSP-9330 spectrum analyzer has four different remote control interfaces: GPIB, RS-232, LAN,and USB.
The remote control interface can be set by pressing:
System → More 1/2 [F7] → RmtInterface Config [F1].
This will allow you to set up the GPIB Address, LAN IP Address, RS-232 Baud Rate and USB
Mode.
You can follow the following instructions to ensure that the spectrum analyzer is successfullyrecognized by the PC.

USB Interface→As can be seen above, to perform remote control via the USB interface, the USB Mode should bechanged from Host to Device so that the spectrum analyzer can be detected by the PC.
You can check that the spectrum analyzer IVI driver is recognized by the PC by going to theWindows Device Manager via the Windows Control Panel.

5SpectrumShot Quick Start Guide

RS232 Interface

If you need to control the spectrum analyzer using the RS-232 interface, the RS-232 Baud Rateshould be set first. The spectrum analyzer has a default baud rate of 115200.
You can use the NI 488.2 software to verify whether the connection is successful. You can also
set the Baud Rate to 115200 in NI 488.2. Make sure to use the correct COM port. The COM port
used depends on the PC. In the diagram below for example, we have used COM port one.

To check that data can be read from the spectrum analyzer, you can go to the NI 488.2
Input/Output setting and execute the *IDN?\n command.

6

Remote Control Interface Setting

LAN Interface→→→

If you need to control the spectrum analyzer using the LAN interface, the IP address must be
set first. By default, the IP address setting is set to DHCP. When using DHCP an Ethernet Hubor Switch will automatically detect a DHCP device.

If you need to manually set the IP address to directly connect with a computer, please follow
the figures shown above. After setting the spectrum analyzer IP address, select Apply [F6] tofinish the setup.
Besides manually setting up spectrum analyzer IP address, the IP address on the PC should beunder the same domain, please refer to the figure below.

7SpectrumShot Quick Start Guide

You can ping the IP to verify whether the connection is successful or not. Please refer to thediagram below that shows a successful connection.

You can also use NI 488.2 software to verify whether the connection has been completed. Pleaserefer to the diagram below.

To check that data can be read from the spectrum analyzer, you can go to the NI 488.2
Input/Output setting and execute the *IDN?\n command.

8

Remote Control Interface Setting

GPIB Interface

If you need to control the spectrum analyzer using the GPIB interface, the GPIB address mustbe set first. By default, the GPIB address is 3. GPIB is an optional extra.

If you need to use the NI GPIB to USB Adaptor (GWInstek GTL-251), then the NI-488.2 drivershould be installed in advance.
You can use the NI 488.2 software to verify whether the connection is connected successfully,
the procedure is similar to the LAN verification above.
The default interface for SpectrumShot is RS-232. When a PC cannot recognize the spectrum
analyzer USB or GPIB Modules, ‘Invalid’ will be displayed on the USB and GPIB interfaces on
SpectrumShot.
If the RS-232 COM Port interface is used, the RS-232 Baud Rate in SpectrumShot needs to be thesame as the baud rate shown for the COM port used by the spectrum analyzer.

When the PC recognizes the spectrum analyzer, the USB interface will be valid and ready to use
when SpectrumShot is turned on.

SPECTRUMSHOT SOFTWARE EMI
PRE-TEST MODE
The default mode of SpectrumShot is EMI Pre-test mode.

10

SpectrumShot Software EMI Pre-test Mode

You can select the required CISPR EMI regulation, including conduction and radiationmeasurement within SpectrumShot.

If you wish to establish related regulations, you can set these by pressing the ‘Edit’ button, then‘New’.

The default Detector is Normal detector, which can switched toPositive peak detector to search the peak point.

11

SpectrumShot Quick Start Guide

The default Scale is 10dB / div.

The default Ref level is 107dBuV (0dBm). The preamplifier will beturned on while the Ref Level is equal to or less than 77dBuV (-30dBm).
When performing a general conduction test, the Ref Level is set
between 117~107dBuV. However, the Ref Lev is set below 77dBuV
when performing radiation measurements as this is mainly used formeasuring weak interference signals.
Take the lighting regulation EN55015 for instance. If you wish to see the Quasi-peak andAverage Limitation line simultaneously, you can tick the box next to ‘Additional’ in order todisplay the Average Limitation line. You may also choose one option from the ‘Fail Mask’column if you need to run a PASS/FAIL judgment on the limitation line.

Press the12button after finishing all the settings.

SpectrumShot Software EMI Pre-test Mode

Press the green "play" button to execute the EMI Pretest mode and to
perform a continuous sweep or select the ‘camera’ button to a run
single sweep.
Press the orange "stop" button to stop the sweep function on theexecution screen of SpectrumShot.
“INSERT TRACE MODE CLEAR & WRITE MAXHOLD screenshot”
Clear and Write: The spectrum analyzer continuously updates the display with each sweep.
MaxHold: The maximum points are maintained for the selected trace. The trace points areupdated for each sweep if new maximum points are found.
Take Broadband Biconical Antennas for example. If you need to insert a probe factor or atransducer factor, you can fill in the information in this column and save.

If you know the insertion loss of the cable, LISN, or pulse limiter, it can be inserted and storedin this column.

13SpectrumShot Quick Start Guide

The Gain value should be set below zero when you connect the Spectrum Analyzer withexternal pre-amplifier.

The Probe, cable loss and Pre-amp settings are saved in a *.csv format, which can be opened andedited by Microsoft Excel.
You can recall the Probe, cable loss and Pre-amp settings after restarting SpectrumShot.

14

SpectrumShot Software EMI Pre-test Mode

You can search the frequency and amplitude of the ‘Warning or Fail’ masks under the Peak
Table option. Here, the the Probe factor, Cable loss or Preamp factor may also be shown on thediagram. The Peak Table option will search for 20 peak points in the test result.

When some frequency points exceed the Fail/Warning Mask, “Warning” or “Fail” will be
displayed on the screen.

15

SpectrumShot Quick Start GuideThe peak points can be user-defined with the Edit Peak Table function. You can directly click
the SpectrumShot test result with a mouse or fill-in the frequency column. Refer to the graphdemonstrated below.

You can tick the ‘Open Interval’ check box in the Peak Search panel. A purple-coloredbackground will be displayed on the screen to indicate the bandwidth.
You can use the mouse on the purple background to redefine the bandwidth of the Add Peak
Search function.

If you need to compare the test results from different DUTs, the test result can be saved as*.CSV file format.

→When a *.CSV file is recalled to compare test results, a maximum 10 of test results can bedisplayed at the same time.

→16→SpectrumShot Software EMI Pre-test Mode

The following is a comparative test result. You can select the “Select View Trace” button toreview the spectrum analyzer setting information for Trace 1.

If you want to store the test result of a DUT in a text file, you can press the ‘Save to rtf’ button.
The tables will then be saved in the rich text file format (*.rtf). An informative description of
DUT can be entered and saved under the “Title” tab.

If you need to save the test result as a graph, you can select the ‘Save As’ button to store theresult as a *.png file. These files have two save options, Normal or Save Toner.

→You may click the ‘Print Preview’ button to preview the graph before printing out or you canclick the ‘Print’ button to print the screen directly.
