Table 5-4: Meaning of suffixes
Suffix
No. Content of data buf-
fer Description
1 Frequency values Raw data: X values, given in the basic unit Hz, to which all levels or
degree values of the raw data from suffix 10 and higher refer.
The SCPI command "TRACe:SWEep<i>:LOAD:AX?" is used to read
out the trace data in the selected unit.
"TRACe:SWEep<i>:LOAD:COUNt:AX?" is used to determine the num-
ber of available values. Correspondence to the SCPI commands is
shown again in
SYSTem:MEMory:DATA<n3>
on page 826.
2 Fct Swp1 TrA Trace data in the basic unit of the 8 sweep graphics.
For the measurement function "Freq. Response", the data set contains
level values in V or FS; for "Phase Response", the data set contains
values in degrees; for"Level THD", the data set contains level values in
V or FS; for "THD", the data set contains values in %.
The SCPI command "TRACe:SWEep<i>:LOAD:AY|BY?" is used to
read out the trace data in the selected unit.
"TRACe:SWEep<i>:LOAD:COUNt:AY|BY?" is used to determine the
number of available values. Correspondence to the SCPI commands is
shown again in
SYSTem:MEMory:DATA<n3>
on page 826.

10 Ch1 freq. response Raw data of the "Freq. Response" function, measured on channel 1.
Level values (RMS) over frequency in the basic unit V or FS.
11 Ch1 phase response Raw data of the "Phase Response" function measured on channel 1.
Degree values over frequency in the basic unit degrees.
12 CH1 frequency
response of harm. d2 Raw data of the harmonics, measured on channel 1.
Level values (RMS) over frequency.
The values are always available in the basic unit V or FS. The data
buffers of the unused harm. remain empty and, when queried, return
the NaN value "3.38".

monics, measured on channel 2.
