#4
Number of digits (= 4 in the example) of the following number of data bytes
1024
Number of following data bytes (= 1024 in the example)
<Value>
4-byte floating point value
Reading out data in binary format is quicker than in ASCII format. Thus, binary format
is recommended for large amounts of data.

Programming Example: Configuring a Spectrogram
This example demonstrates how to configure a spectrogram for a basic frequency
sweep in a remote environment. The spectrogram is displayed in addition to the spec-
trum display, in a new window. In addition, the usage of special spectrogram markers
is demonstrated (see
Chapter 8.8.8.6, "Marker Search (Spectrograms)"
Basic trace settings are demonstrated in the
Chapter 8.6.14, "Programming Example:
Performing a Basic Frequency Sweep"
//-----------Preparing the Measurement ------------
*RST
//Resets the instrument
LAY:ADD? '1',BEL,SGR
//Displays a new window below window 1 and activates spectrogram display.
//The new window name is returned as a result: '2'.
//The spectrogram is updated with each new sweep.
INIT:CONT OFF
//Selects single sweep mode.
//--------------Configuring the Spectrogram--------------
CALC:SGR:CLE
//Clears the displayed spectrogram to start a new one.
CALC:SGR:CONT ON
//Configures a continuous spectrogram for a series of measurements.
//The display is not cleared when a new measurement is started.
CALC:SGR:FRAM:COUN 100
//Sets the number of frames to be recorded per sweep to 100.
CALC:SGR:HDEP 1000
//Sets the number of frames to be stored to 1000 (=10 sweeps)
CALC:SGR:TST ON
//Activates a time stamp for each frame.
//--------------Configuring the Color Map----------------
DISP:WIND:SGR:COL GRAY
//Defines a gray-scaled coloring: low values light gray, high values dark gray.
DISP:WIND:SGR:COL:LOW 30
