Mask Test Commands
IMPedance
IMPedance
Command :MTESt:IMPedance {NONE | IMP75 | IMP100 | IMP110 |
IMP120}
The :MTESt:IMPedance command sets the desired probe impedance of the
channel being used for mask testing. This impedance value is used when
starting a mask test to determine whether or not the correct Infiniium probe is
connected and in the case of the E2621A if the switch is set to the correct
impedance value.
Infiniium has an AutoProbe interface that detects probes that have Probe ID
resistors. If one of these probes is connected to the channel being mask tested
and is not the correct probe for the selected impedance, a warning dialog box
appears when the mask test is started from the human interface.
This command is meant to be used in the setup section of a mask file.
NONE
Disables the probe impedance check.
IMP75
Enables the probe impedance check for the E2622A probe.
IMP100
Enables the probe impedance check for the E2621A probe with the switch set
to the 100 ohm position.
IMP110
Enables the probe impedance check for the E2621A probe with the switch set
to the 110 ohm position.
IMP120
Enables the probe impedance check for the E2621A probe with the switch set
to the 120 ohm position.
Example
This example sets the probe impedance of the channel being used for mask
testing to 100 ohms.
