For the running sequence, the power supply output for Example 2 should look like the
following:
Figure 12-2

Power Supply Output for Example 2
Once the ramp goes down to 2 volts, the sequence stops, and the unit remains at the
state of the last command within the sequence.
EXAMPLE 3
Issue
*RST
to establish a known state.
In this third example, redefine SEQ1 so that it calls SEQ2 as a subroutine.
To modify SEQ1 requires that it be deleted, and re-written. Overwriting a completed,
existing sequence is not allowed by the SCPI command interface for code readability
reasons. Even though overwriting is not permitted, re-writing is permitted after a
sequence has been deleted. Delete the SEQ1 sequence as follows:
PROG
<n>
: NAME “SEQ1”
PROG
<n>
:DEL:SEL
That deletes SEQ1.
Now create a new SEQ1 that calls SEQ2 as a subsequence.
PROG
<n>
: NAME “SEQ1”
PROG
<n>
:MALL DEFAULT
PROG
<n>
:DEF 1, VIMODE, 3, 4, 11, 10
//go to 3 volts, 4 amps, 11 volts ovp,
for 10 sec
PROG
<n>
:DEF 2, RAMPTOV, 3, 5, 4, 11, 10
//ramp from 3 volts to 5 volts in
10 sec
PROG
<n>
:DEF 3, VIMODE, 5, 4, 11, 10
//hold 5 volts for 10 sec
PROG
<n>
:DEF 4, RAMPTOV, 5, 3, 4, 11, 10
//ramp from 5 volts to 3 volts in
10 sec
PROG
<n>
:DEF 5, VIMODE, 3, 4, 11, 10
//hold 3 volts for 10 sec
PROG
<n>
: DEF 6, SUBCALL, “SEQ2”
//call SEQ2 as a subsequence
10 volts for 5 sec
Ramp down to 2
volts in 9 sec
Notice that after the RETURN
statement is encountered in this run of
SEQ2, since SEQ2 is being used as a
primary sequence, the RETURN acts
like a STOP statement and stops
running the sequence.
