3.25 :TSEQuence Subsystem
The commands in this subsystem are used to configure and control the built-in test sequences,
and are summarized in Table 3-16. Detailed information on the test sequences are provided in
paragraph 2.14.
In your test programs, use the *OPC? command before arming (:TSEQuence:ARM) the test.
The *OPC? command allows previous command operations to finish before arming the test.
Failure to do so may cause unfavorable results. The programming example at the end of this sub-
system demonstrates how to use the *OPC? command.
You should use SRQ to indicate when a test sequence is finished. The programming example at
the end of this subsystem generates an SRQ when the buffer is full (test sequence finished). The
readings are then sent to the computer where they are displayed.
3.25.1 General Test Sequence Commands
:ARM
:TSEQuence:ARM Arm selected test sequence
Description This action command is used to arm the selected test sequence (see :TYPE). The test will start
when the programmed source event occurs (see :TSOurce). When using this command for the
Alternating Polarity High Resistance/Resistivity Measurements, wait at least 0.3 seconds before
using the *TRG trigger command.
:ABORt
:TSEQuence:ABORt Step test sequence in process
Description This command is used to stop a test sequence that is in process. You can start it again by arming
(:ARM) the test and providing the programmed source event (:TSOurce).
:TYPE <name>
:TSEQuence:TYPE <name> Select test sequence
Parameters <name> = DLEakage Diode Leakage Test
CLEakage Capacitor Leakage Test
CIResistance Cable Insulation Resistance Test
RVCoefficient Resistor Voltage Coefficient Test
SRESistivity Surface Resistivity Test
VRESistivity Volume Resistivity Test
SIResistivity Surface Insulation Resistance Test
SQSWeep Square Wave Sweep Test
STSWeep Staircase Sweep Test
ALTPolarity Alternating Polarity Resistance/Resistivity Test
Query :TYPE? Query selected test sequence
Description This command is used to select the desired test sequence. When test sequence is started (see
:TSOurce), the selected test will run according to how it is configured. The commands in para-
graphs 3.25.2 through 3.25.15 are used to configure the test sequences.
