WaveLink Series Differential Probe (13-25 GHz)
84 WL-HBW-A-OM-E Rev B
Offset
The offset for the WaveLink High Bandwidth Series probes (D1305-A, D1605-A, D2005-A, and D2505-
A) is in the probe amplifier. Thus, these probes have full offset capability over their entire V/Div
range.
When the WaveLink series probe is used with a Teledyne LeCroy WaveMaster 8 Zi / Zi-A or similar
oscilloscope equipped with ProLink or 2.92mm interface, the probe offset is controlled with the
channel OFFSET knob.
Sometimes it may be desirable to display a waveform as a reference signal where a large display
amplitude may not be necessary. Perhaps a timing reference when amplitude details are not
needed. In such a case, the oscilloscope's zoom function can be used to reduce the displayed height
of the reference signal. (Refer to your oscilloscope's online help for operation of the zoom function.)
Dynamic Range
WaveLink High Bandwidth D1305-A, D1605-A, D2005-A, and D2505-A probes have no gain or
attenuation control. However, WL-PLINK-A and WL-2.92MM do provide gain and attenuation
controls.
The system attenuation is fixed at approximately 3.5 to 4.5, depending on model. The actual gain
value for each probe is indicated in the probe dialog box, which is displayed when the probe is
connected to the scope.
The WaveLink series probes are always DC coupled (no AC coupling is provided). Therefore, care
must be exercised to avoid exceeding the common mode range. Because the common mode signal
is rejected by the probe and is not displayed, changes in the amplitude of the common mode
component are not apparent to the user. Exceeding the common mode range may introduce
distortion to the probe's output signal.
