Channel Patterns - Keithley 3700A Series Reference Manual

Series 3700A System Switch/Multimeter Reference Manual Section 5: Switching and scanning
To set up labels from the front panel:
1. Display a channel (you might need to press DISPLAY first).
2. Select the channel for which you want to set labels.
3. Press CONFIG, then press CHAN.
4. Use the navigation wheel to select LABEL, which allows you to set the label that will show on
the front-panel for the specified channel.
5. Change the name using the navigation wheel .
6. Press the navigation wheel to save the change.
To set up labels from the web interface:
1. From the list on the left, select the slot that contains the channel you want to set up a label on.
2. Right-click the channel.
3. In the Label box, enter the label.
4. Click OK.
To set up labels from the remote interface use the channel.setlabel() (on page 11-91) command.
You can use labels to refer to the channels in commands. For example, if you set the label for
channel 3005 to "start", you could use "start" to close and open the channel.
This is shown in the following example:
channel.setlabel("3005","start")
channel.close("start")
print(channel.getclose("allslots"))
Pole settings
The BACKPLANE RELAYS option provides a list of backplane relays to control when performing a
switch-only operation on a single channel or range of channels. This attribute is not applicable to
channel patterns. Refer to

Channel patterns

(on page 5-19).
The POLE SETTING option for multiplexer (MUX) channels indicates if the paired MUX channel
should be included when performing a close or open operation on channel. In a switching module that
has 60 channels, the Series 3700A automatically pairs channels 1 through 30 with channels 31
through 60 (respectively) when the pole setting for a channel is set to 4-pole. Once you configure the
pole setting of a switching channel for 4-pole, the associated paired channel becomes unavailable for
switching operation. For example, assume 3003 is set to 4-pole and its paired channel is 3033. Now,
you cannot set attributes or perform close/open operations on 3033. A paired channel settings conflict
error generates if you specify channel 3033 for a close/open operation.
Matrix channels have fixed pole settings. Multiplexer channels pole settings may be changed.
Channel patterns
You can use channel patterns as a convenient way to refer to a group of switching channels and
backplane relays with a single alphanumeric name. When you perform close or open operations on a
channel pattern, only the channels and analog backplane relays that are in the channel pattern are
affected.
There is no speed difference when performing close and open operations on channel patterns
compared to performing the same operations on individual channels or a list of channels.
