4. Set the unit to 100 Hz. Verify that the capacitance reading is close to the value
measured above and within the tolerance stated above. Repeat for 120 Hz. D
values should be below 0.0001.
5. Repeat for 10 kHz. At 10kHz, the tolerance is 1.15%. For 100 kHz the tolerance
is 1.25%. D values should be below 0.001 for 10 kHz and 0.01 for 100 kHz.

Performance Tests

These tests are intended to measure the 9216A's conformance with its published
specifications. These test results, along with the results of the functional tests, can be
recorded on the test sheet at the end of this manual.

Necessary Equipment

Instrument
Time Interval Counter
DC/AC Voltmeter
Resistance decade box
Capacitance decade box
Test conditions: at least 30 minutes of warm-up time, and a temperature in the range
of 23C  5 C.

Frequency Accuracy

This test measures the accuracy of the different output frequencies. They should be with-
in 0.01% (100 ppm) of the nominal value.
1. Set the Z-9216 to its default conditions by pressing the key sequence RCL 0 EN-
TER. Set the unit to constant voltage mode, 1 kHz test frequency, and remove
any part from the fixture.
2. Install the BNC adapter on the fixture. Connect the IH lead to the frequency
counter.
3. Verify that the frequency counter reads 1 kHz  0.1 Hz (+0.01%). Record the re-
sult.
4. Repeat step 3 at 100 Hz, 120 Hz, 10k Hz and 100 kHz. The frequencies should
all be within 0.01% of the nominal frequency. Record the results.

Amplitude Accuracy

This test measures the amplitude accuracy of the drive output. It should be within
2.0% of the nominal value for all of the amplitude settings.
1. Connect the AC/DC voltmeter across the two sides of the fixture. A small piece of
wire inserted in each side of the fixture is a convenient way to connect the DVM.
Do not connect either end to ground. Set the DVM to AC volts, auto ranging.
