(Command/Query)
The SYST:SET <block> command transfers the configuration from the computer to the device.
<block> is a finite data number preceded by the heading #an with n, the data number and a, a
figure indicating the number of figures making up n.
To the question SYST:SET?, the device transfers the current configuration to the computer.
Response format: <block> <NL>
(Command/Query)
The SYST:TIME <NR1>,<NR1>,<NR1> command sets the time of the instrument.
The possible values are:
0
to
23
for the hour range (1st range).
0
to
59
for the minute range (2nd range).
0
to
59
for the second range (3rd range).
To the question SYST:TIME?, the instrument returns the hour.
Response format:
< HH,MM,SS ><NL>
avec H = hour, M = minute, S = second.
(Query)
To the question TRAC:CAT?, the device returns the list of active signals.
# TRAC:CAT?
reply <NL> when no signal is active.
reply INT1 <NL> when only signal 1 is active.
reply INT1,INT3<NL> when signals 1 and 3 are active.
(Command/Query)
The TRAC:LIM <abscissa1>,<abscissa2>,<step> command sets the left and right limits and
the step of the data to be transferred.
<abscissa1>,<abscissa2>,<step> are parameters using format NR1.
Their default value is 0, 2499 and 1.
To the question TRAC:LIM?, the device returns the left and right limits and the step of the data
to be transferred.
(Query)
To the question TRAC? <INT{1|2|3|4}>, the device transfers the selected trace to the
computer.
Response format: <block><NL>
<block> is a data block, the format of which is set by the FORMat:DINTerchange and
FORMat[:DATA] commands.
It contains the value of the 2500 samples encoded on 4 bytes, as follows (bit 31 = MSB):
The validity byte contains 3 data bits:
with :
I :
Invalidity, the sample is invalid if equal to 1
A : Age, used in slow mode, this sample is validated
E : Extrapolated, the sample is the result of an extrapolation if equal to 1.
(Command/Query)
The TRIG:SEQ{2|3}:DEL <time|MAX|MIN|UP|DOWN> command
in sequence 2 (Pulse) sets T1, the pulse time in following cases :
« t > T1 »,
« t > T1 and t < T2 »,
« t < T1 or t > T2 »
in sequence 3 (trig-after-delay): sets the trigger delay on main source
