Datasheet

For compliance testing of the HDMI and DisplayPort standards, the
P77C292MM and P7700 series probes are fully supported in Tektronix'
automated measurement suites for these standards. With the P77C292MM
adapter attached, a P7700 series probe can provide the DC termination
voltage required by HDMI and other high-speed communication standards.
The termination voltage can be set manually or automatically using voltage
sense circuitry in the P7700 probe and covers a range of ±4 V.

Automatic probe and tip identification and
AC calibration
The P7700 Series probes automatically identify the accessory connected to
the probe. When the probe and tip are attached to an oscilloscope, they are
recognized and a unique DSP filter providing a calibrated response is
enabled. All calibration and filter calculation is based upon a unique set of
s-parameters stored in the probe and tip.
These unique filters also de-embed probe parasitics from the
measurement. Creating probe and tip specific filters is critical as
bandwidths increase. At high bandwidth, small variations in the signal path
can lead to significant variation in frequency response which cannot be
corrected using a nominal DSP filter.
The P77BRWSR accessory extends the calibration further. As the spacing
of the browser's tips is adjusted, the change in opening is automatically
recognized by the probe and oscilloscope. Using the value of the tip
spacing, a width specific DSP filter is used to calibrate the probe's
response.
The automatic recognition of the probe and tips and the automatic filter
selection eliminates the risk of manually selecting the wrong filter and
improves your efficiency.
Signal fidelity
You can be confident in the signal fidelity of your measurements. The
innovative new probe design uses SiGe technology to provide the
bandwidth and fidelity needed today and in the future.
The P7700 Series probe architecture provides:
An active buffer amplifier on the tips with the solder-in tips' probe input
only 3.2 mm from the input
Excellent step response and low insertion loss up to 20 GHz
Low-DUT loading with 100 kΩ (DC) and 0.4 pF (AC) performance
High CMRR
Low noise
Performance you can count on
Depend upon Tektronix to provide you with performance you can count on.
In addition to industry leading service and support, these probes are
backed by a one year warranty.
