Description:
Macros for operating the PTC (pyramid technical consultants inc.) I400 4-channel electrometer
|
Documentation:
OVERVIEW
This macro set allows to control I400 units in spec and configure
their signal inputs as pseudocounters.
More than one I400 unit can be operated through this macro set.
EXAMPLE
- i400setup mydev 0 c1=curr1 c2=curr2 c3=curr3 c4=curr4
- Configures an I400 unit connected to the spec serial line #0 and
associates its four input channels to the pseudocounters
curr1, curr2, curr3 and curr4.
- icplussetup bpm0 2 cx=beamX cy=beamY
- Configures an I400 unit connected through the serial line #2 and
associates normalised current differences to the pseudocounters
beamX and beamY.
- i400show
- Display the list of I400 units currently configured.
SETUP
Serial line in spec config has to be set as raw, 19200 baud
The mode rotary switch on the I400 unit has to be set to 8.

Macros:
i400setup
Usage: i400setup <i4name> <serline> [<parameter>=<value> ...]
Configures a I400 connected to <serline> with the name <i4name>.
The following optional parameters can be also set.
- Valid parameters:
- address=<addr>
- This parameter allows to address a particular unit when the serial
line is shared by several IC-PLUS units. By default, the address
is read from the unit assuming only one unit on the serial line.
- c1=<cnt_mne>
- c2=<cnt_mne>
- c3=<cnt_mne>
- c4=<cnt_mne>
- If <cnt_mne> is a valid counter mnemonic, it gets configured as
a pseudocounter loaded with the current in the corresponding
channel (1 to 4).
The "Scale Factor" value in the spec config file applies.
- ci=<cnt_mne>
- If <cnt_mne> is a valid counter mnemonic, it gets configured as
a pseudocounter loaded with sum of all channels
ci= c1+c2+c3+c4
The "Scale Factor" value in the spec config file applies.
- cx=<cnt_mne>
- cy=<cnt_mne>
- If <cnt_mne> is a valid counter mnemonic, it gets configured as
a pseudocounter loaded with the normalised current difference:
cx= ((c2+c3)-(c1+c4))/(c1+c2+c3+c4)
cy= ((c1+c2)-(c3+c4))/(c1+c2+c3+c4)
(x,y) defined for a geometry like:
y
^ c1 | c2
|---------> x
| c4 | c3
The "Scale Factor" value in the spec config file applies.
- samples[=1]
- Sets the number of sub-samples per integration period
i400samples
Usage: i400samples <i4name> <samples>
Sets the number of sub-samples taken during intergration period
for the i400 unit <i4name>
i400capacitor
Usage: i400capacitor <i4name> <capacitor>
Sets feedback capacitor to low value (0) or high value (1)
i400show
Usage: i400show
Shows the list of I400 units configured
