HFP1500 High Frequency Probe

Operation
Handling the Probe
Exercise care when handling and storing the probe. Always handle the probe by the probe body or
compensation box. Avoid putting excessive strain or exposing the probe cable to sharp bends.
Connecting the Probe to the Test Instrument
The HFP1500 probe has been designed for use with Teledyne LeCroy’s WavePro™, Waverunner™
and LC oscilloscopes equipped with the ProBus interface. When you attach the probe output
connector to the oscilloscope’s input connector, the oscilloscope will recognize the probe, provide
proper termination and activate the probe control functions in the user interface.
Connecting the Probe to the Test Circuit
To maintain the high performance capability of the probe in measurement applications, care must
be exercised in connecting the probe to the test circuit. Increasing the parasitic capacitance or
inductance in the input paths may introduce a “ring” or slow the rise time of fast signals. Input leads
which form a large loop area will pick up any radiated electromagnetic field which passes through
the loop and may induce noise into the probe input.
Using one of the available accessories makes the HFP1500 probe with its small profile and low mass
head ideally suited for applications in dense circuitry.
Operation with a Teledyne LeCroy Oscilloscope
When the HFP1500 probe is connected to any Teledyne LeCroy oscilloscope, the displayed scale
factor and measurement values will be automatically adjusted. Control through the oscilloscope’s
interface can be found in the ’Coupling’ menu of the channel to which the probe is connected.
Turning the Volts/Div knob will control the oscilloscope’s scale factor to give full available dynamic
range up to 2 V/div.
Use with Older Teledyne LeCroy Instruments
When used with Teledyne LeCroy instruments with software version lower than 8.7.0, the
oscilloscope will provide the correct scale factor but no AutoColor ID. With V/div settings greater
than 2 V/div, it is possible to display clipped waveforms on screen.
