(Command/Query)
The CALC:MATH <(function)> command defines and activates the mathematical function.
<function> is the definition of the mathematical function. Possible functions are: (-A), (-B), (A+B), (A-B),
(A*B) ou (A/B).
<(multiplier)> is the multiplier to be applied to the function. Possible multipliers are (1), (*2), (*5), (/2)
ou (/5).
Note: (A-B),(*2) subtract the channel A to the channel B and multiplies the result by 2 (acc. to following
calculation : (A-B)*2).
To the question CALC:MATH?, the instrument returns the mathematical function and its multiplier.
Response format:
<(function),(multiplier)><NL>
(Command/Query)
The command DISP:TRAC:Y:PDIV{[1]|2} <scale|MAX|MIN> sets the value of the probe coefficient for
the selected signal.
<scale> is a value at NRf format.
To the question DISP:TRAC:Y:PDIV{[1]|2}?, the instrument returns the value of the probe coefficient
for the selected signal.
(Command/Query)
The DISP:TRAC:Y:LAB{[1]|2} <"label"> command determines the unit of the selected signal.
The unit is selected among the upper-case letters of the alphabet (A to Z), and is composed of a name
up to 3 letters.
To the question DISP:TRAC:Y:LAB{[1]|2}?, the instrument returns the unit of the selected signal.
Channel 3 corresponds to the MATH function for which the sensitivity is accessible in reading only.
With SCPI he various trigger modes can be accessed with the sequence concept.
The instrument has several trigger modes, thus several sequences:
Sequence 1 : Trigger on edge (EDGE)
„
Sequence 2 : Trigger on pulse width (PULse)
„
The sequence can be selected with the commands: INIT:CONT:NAME or NIT:NAME

(Command/Query)
The TRIG:SOUR <INTernal{1|2}> command determines the main trigger source of the instrument.
INTernal{1|2} corresponds to the A and B channel instrument.
To the question TRIG:SOUR?, the instrument returns the main trigger source used in.
(Command/Query)
The TRIG:FILT:HPAS <1|0|ON|OFF> command validates or devalidates the reject of the low frequencies
associated to the main trigger source.
1|ON: activates the reject of the low frequencies (LF Reject coupling)
„
0|OFF: deactivates the reject of the low frequencies; the DC coupling is then activated.
„
To the question TRIG:FILT:HPAS?, the instrument returns the activation status of the low frequencies
reject associated to the trigger source.
