DC level – a reference level
Trigger Enabled – can be used as a gating function to trigger another instrument when the oscilloscope
is ready
Pass/Fail – allows you to set a pulse duration from 1 ms to 500 ms; generates a pulse when pass/fail
testing is active and conditions are met.
Aux Output Off – turns off the auxiliary output signal

Auxiliary Output Setup

1. In the menu bar, touch Utilities, then Utilities Setup... in the drop-down menu.
2. Touch the Aux Output tab.
3. If you simply want a 1 kHz, 1 V square wave, touch the button so labeled.
4. If you want a specialized output, touch one of the buttons under Use Auxiliary Output For.
5. Touch inside the Amplitude field and enter a value, using the pop-up numeric keypad. If you want a TTL level
signal, touch the TTL Level checkbox. The Amplitude field will accordingly become unavailable.
6. If you selected Square Wave, touch inside the Frequency field and enter a value, using the pop-up keypad.
You can set a value from 5.0 Hz to 5 MHz.
7. If you selected Pass/Fail, touch inside the Pulse Duration field and enter a value from 1 ms to 500 ms, using
the pop-up numeric keypad.

PROBES

Your WaveRunner Xi oscilloscope is supplied with one PP008 passive probe for each channel. The PP008 is a
miniature high impedance passive probe. Its high input resistance and low capacitance make it ideal for general
purpose probing of signals with frequency content from DC through several hundred MHz. The PP008 has a large
selection of connection accessories, supplied standard with the probe and available from LeCroy as optional
accessories.
The PP008 is designed for use with 600 MHz and lower LeCroy WaveRunner Xi series oscilloscopes. Refer to the
PP008 Instruction Manual.
LeCroy also offers a variety of passive and active probes for use with your WaveRunner Xi Series oscilloscope.

Current Probes measure the current passing through a wire. They do not use the traditional
Current
probing style of placing a tip onto a test point. Instead, a wire is placed inside of the jaw of the
Probes
probe, which then allows the probe to measure the current (in Amps).
There are two different types of active probes: single-ended and differential.
Single-ended: A single-ended active probe is associated with measuring voltages at high
frequencies. Measurement with an active probe requires a test point and a ground point. The
Active
ground (also called earth) acts as a zero reference for the test point measurement.
Probes
Differential: Differential active probes are like two probes in one. Instead of measuring a test point
in relation to a ground point (like single-ended active probes), differential probes measure the
difference in voltage of a test point in relation to another test point.
Passive probes measure voltages at lower frequencies (<400 MHz). They have higher input
capacitance (input C) and do not need power to operate (unlike active probes). At higher
Passive
frequencies, higher input capacitance loads the test circuit, attenuating the signal. This is why
Probes
active probes are used in high frequency applications. Passive probes also measure voltage in
reference to ground.
High
These are active single ended probes that are designed to measure high voltages (safely). They
Voltage
measure the voltage in reference to ground.
