5.5.5 Step functions
When a list of memory addresses has been filled with volta
e and current
settin
s, it can be used in one of the followin
ways:
1) AUTO_STEP OFF:
This will invoke the manual step function, i.e., the next step is initiated by
the operator. For instance by manually steppin
throu
h a list of
predefined volta
es and currents, a test pattern of volta
e and current
settin
s will be
enerated. The manual steppin
will be executed for all
enabled output channels. Refer to section "Manual step function" on this
pa
e.
2) AUTO_STEP ON:
This will invoke the automatic step function, i.e. the next step is initiated
when the interval time has expired. For instance by automatically steppin
throu
h a list of sequential volta
es and currents, a volta
e/current ramp
function will be executed. The start and stop address of the sequential list
and the interval time between two consecutive steps can be pro
rammed.
Steppin
can be done in one of the followin
ways:
3) CONTINUOUS_STEP OFF:
The predefined sequence of memory addresses is executed only once.
4) CONTINUOUS_STEP ON:
The predefined sequence of memory addresses is executed continuously,
i.e., repeatedly from start to stop address.
Steppin
will be executed for all enabled output channels. Refer to section
"Automatic step function" on the next pa
e.
Manual step function:
The manual step function can be executed locally, usin
the key.
The AUTO_STEP function can be set ON or OFF via the STEP MENU under the
key.
Example:
• REQUIREMENTS :
Step manually throu
h the predefined list of volta
e and current settin
s,
stored at the memory addresses 20 to 40. The volta
e and current settin
s
must be output for channel 1. Output channel 2 must be disabled.
