* Specific instrument errors:
(-399 to -300)
They indicate that an abnormal error has been detected during execution of a task, and causes
event register bit 3, called DDE, Device Dependent Error to be set to 1.
-300 : Device-specific error
-321 : Out of memory
-350 : Queue overflow
-360 : Communication error
* Query errors:
(-499 to -400)
They indicate that an abnormal error has been detected during execution of a task, and cause
event register bit 2, called QYE, QuerY Error, to be set to 1.
-400 : Query error
SYSTem:KLOCK (Command/Query)
The SYST:KLOCK <0|1|ON|OFF> command locks the front face.
To the question SYST:KLOCK?, the instrument returns the lock status of the front face.
SYSTem:SET (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>
SYSTem:TIME (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.
TRACe:CATalog (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.
TRACe[:DATA] (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):

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.
