voltage (MEAS-V) is then applied and, after a specified time
(MEAS-TIME), the Model 6517A measures the resistance
and stores the reading in the buffer.
This test is selected and configured from the CONFIGURE
SEQUENCE menu (SIR). See paragraph 2.14.2 for details.
Sweep Tests (Square Wave and Staircase)
The sweep tests are not geared to any specific application. These
voltage/measure sweeps can be used for any type of measure-
ment; volts, amps, ohms or coulombs. Thus, make sure to select
the measurement function before running one of these tests.
The Square Wave Sweep Test allows you to make a series of
measurements at an alternating high and low voltage level.
When the test is configured, you specify the high voltage lev-
el (HI-LEVEL), the time spent at the high level (HI-TIME),
the low level voltage (LO-LEVEL), the time spent at the low
level (LO-TIME), and the number of cycles to repeat (CY-
CLE COUNT). Figure 2-54 shows an example using the de-
fault test parameters. When the test is run, 20 measurements
will be performed (at each high and low level) and stored in
the buffer. This test is selected and configured from the
CONFIGURE SEQUENCE menu (SWEEP; STAIRCASE).
See paragraph 2.14.2 for details.
The Staircase Sweep Test allows you to make measurements
at staircased voltage levels. When the test is configured, you
specify the START voltage, the STEP voltage, the STOP volt-
age and the delay (STEP TIME) between steps. Figure 2-55
shows an example using the default test parameters.
When the test is run, 10 measurements will be performed
(one at each voltage step) and stored in the buffer. This test
is selected and configured from the CONFigure SE-
QUENCE menu (SWEEP; STAIRCASE). See paragraph
2.14.2 for details.
