[SENSe:]ADEMod:PM:RPOint[:X]
<Time>
This command determines the position where the phase of the PM-demodulated signal
is set to 0 rad. The maximum possible value depends on the measurement time
selected in the instrument; this value is output in response to the query
ADEM:PM:RPO:X? MAX
.
Parameters:
<Time>
0 s to measurement time
*RST:
0 s
Example:
ADEM:PM:RPO 500us
Sets the position where the phase to 0 rad setting to 500 µs.
11.7.4 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
. 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.
11.7.5 Reference: ASCII File Export Format
Trace data can be exported to a file in ASCII format for further evaluation in other
applications. This reference describes in detail the format of the export files for result
data.
The file consists of the header containing important scaling parameters and a data sec-
tion containing the trace data. Optionally, the header can be excluded from the file (see
"Include Instrument Measurement Settings"
