E-1
ASCII Format (FORMat ASCII):
In this case the command returns a comma separated list of the measured voltage values in floating
point format (Comma Separated Values = CSV). The number of values returned is 2 * number of
samples, the first half being the I-values, the second half the Q-values.
Binary Format (FORMat REAL,32):
In this case the command returns binary data (Definite Length Block Data according to IEEE 488.2),
with the lists of I- and Q-data being arranged one after the other in 32 Bit IEEE 754 floating point
data. The scheme of the response string is as follows:
#44096<I-value1><I-value2>...<I-value512><Q-value1><Q-value2>...<Q-value512>
with
#4
digits of the subsequent number of data bytes (4 in the example)
4096
number of subsequent data bytes (
# of DataBytes
, 4096 in the example)
<I-value x>
4-Byte-Floating Point I-value
<Q-value y>
4-Byte-Floating Point Q-value
The number of I- and Q-data can be calculated as follows:
8

The offset of Q-data in the output buffer can be calculated as follows:

with LengthIndicatorDigits being the number of digits of the length indicator including the '#'. In the
example above (#44096...) this results in a value of 6 for LengthIndicatorDigits and the offset for the
Q-data will result in 2048 + 6 = 2054.
Characteristics
: *RST value:
--
Note:
Using the command with the *RST values for command
TRAC:IQ:SET the following minimum buffer sizes for
the response data are recommended:
ASCII format: 10 kBytes
Binary format: 2 kBytes
SCPI:
device specific
The command requires that all response data are read out completely before the
instrument accepts further commands.
TRACe<1|2>:IQ:DATA:FORMat
COMPatible
| IQBLock | IQPair
This command sets the data output formatting (using the TRAC:IQ:DATA? command):
COMPatible
512k I data and 512k Q data is alternately transferred
IQBLock
First, all I and then all Q data is transferred
IQPair
I/Q data is transferred in pairs
Example:
"TRAC:IQ:DATA:FORM IQP"
