Query parameters:
<TraceNumber> Trace number.
TRACE1 | ... | TRACE6
Example:
TRAC3:X? TRACE1
Returns the x-values for trace 1 in window 3.
Usage: Query only
Manual operation: See "Spectrum Emission Mask" on page 113

Formats for Returned Values: ASCII Format and Binary Format
When trace data is retrieved using the TRAC:DATA or TRAC:IQ:DATA command, the
data is returned in the format defined using the FORMat[:DATA]. The possible for-
mats are described here.
●
ASCII Format (FORMat ASCII):
The data is stored as a list of comma separated values (CSV) of the measured val-
ues in floating point format.
●
Binary Format (FORMat REAL,32):
The data is stored as binary data (Definite Length Block Data according to IEEE
488.2), each measurement value being formatted in 32 Bit IEEE 754 Floating-
Point-Format.
The schema of the result string is as follows:
#41024<value1><value2>…<value n> with
#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.
11.8.2.6 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 11.8.3.6, "Marker Search (Spectrograms)",
on page 944).
Basic trace settings are demonstrated in the chapter 11.15.1, "Programming Example:
Performing a Basic Frequency Sweep", on page 1088.
