AUX 1 and AUX 2
AUX 1 and AUX 2
Pulse Test
You can output one or more 500 ∝s pulses from AUX 1 or AUX 2 and measure them with an oscilloscope. The number of pulses is selectable. The pulses have a 50% duty cycle, and thus a total period of 1 ms. The amplitude of the signal is roughly 0 to 4 volts. The pulses are not perfect square waves. The leading edge rises higher than 4 volts, then curves down to approximately 4 volts.
Measuring Pulses from AUX 1 or AUX 2
NOTE
NOTE
1.Connect an oscilloscope to the AUX 1 or AUX.
2.Set the scope as necessary to view the waveform described above.
3.Press:
[Select Instr] {85330A} {→ } {TEST} {→ } {AUX 1} or {AUX 2}
4.The message TEST AUXn OUTPUT: # OF TESTS will appear.
5.Use the keyboard to enter the desired number of pulses. You can enter
the number in units or in scientific notation: For example:
100, or 1E2
6. Press the [Return] key. The pulses will appear on the scope.
The 85330A will not perform any other functions during this test. If you enter a large number, such as 1E6, it will take a while to finish. You can abort the test by cycling line power.
To test AUX 2, use the same basic procedure as shown above.
