Retrieve Screen Images

Function Transfer Screen Images from the instrument
Description This example demonstrates how to:
1. Store the current screen image in instrument memory as "D:\PICTURE.PNG"
2. Transfer the memory image file via GPIB or LAN
3. Store the transferred image in the computer's current directory as "C:\PICTURE.PNG"
4. Delete the instrument memory file "D:\PICTURE.PNG"
Language Visual Basic 6

Read Binary Trace Data

Function Read Binary Block Trace data from the instrument
Description This example demonstrates how to:
1. Open a VISA session via GPIB or LAN
2. Modify the timeout value
3. Send the *IDN? query to the instrument, then display the result
4. Change the instrument mode to Spectrum Analyzer
5. Set the Trace data format to REAL,32 or REAL,64
6. Set the instrument to Single Sweep
7. Initiate a sweep
8. Read the trace data and display it
9. Store the trace data to the file "bintrace.txt"
The binary data transfer method is faster than the default ASCII transfer mode, because less data is sent over the bus. For more
information about data formats, see the section "Remote Measurement Functions" in any X-Series Help file or Users &
Programmers Reference PDF.

C, C++

The samples provided are console applications written in C, but these should also be compilable by most C++ compilers.
1. Poll Method for Operation Complete
2. SRQ Method for Operation Complete
3. Set and Query Relative Band Power Markers
4. Set Traces and Couple Markers
5. Phase Noise Trace Math
All the samples use the VISA driver.
