Tektronix P7700 series TriMode Probes

The P7700 Series TriMode probes provide the highest probe fidelity available for real-time oscilloscopes. In addition, with connectivity innovations such as solder down tips with the probe’s input buffer mounted only a few millimeters from the end of the tip, the P7700 series probes provide unmatched usability for connecting to today’s most challenging electronic designs.

P7700 Series TriMode Probes

With TriMode probing one probe setup makes differential, single ended, and common mode measurements accurately. This unique capability allows you to work more effectively and efficiently, switching between differential, single ended and common mode measurements without moving the probe’s connection points.

TekFlex connector technology

The P7700 Series TriMode probes use the new TekFlex connector technology that combines a high speed signal path with power and communication support for an active buffer tip in a single, easy to connect accessory connector. The TekFlex connector has a pinch-to-open design that when open requires minimal force to attach an accessory tip. When the TekFlex connector is closed, it provides a secure connection to the accessory to avoid accidental disconnections.

With the TekFlex connector, the P7700 series probes offer a set of active probe tips with the probe’s buffer amplifier only millimeters from the input connections. The short signal path enabled with the active tips provides high fidelity and a high impedance input. It also minimizes signal loss, capacitance, and additive noise.

Browser accessory for handheld probing

When you need to make a quick measurement or debug a problem, the P7700 series browser accessory provides a simple to use option. With precision engineered tips that are easy to see and position accurately, the P77BRWSR handheld browser accessory enables hand or fixtured probing and is ideal for probing fine pitch components and differential traces with spacing as narrow as 0.2 mm (.008 in).

P77BRWSR handheld browser accessory enables hand or fixtured probing with adjustable tip spacing. Up to 16 GHz bandwidth.

The browser’s tips have a full range of compliance and are adjustable in spacing using a convenient thumb wheel. A headlight on the tip enhances visibility of the probe point and can be switched on and off as needed. The browser tips are constructed of high strength BeCu and super-ceramic resistors1. With 16 GHz bandwidth performance, the P77BRWSR handheld browser accessory enables hand or fixtured probing with signal fidelity and convenience.

Coaxial input (SMA) adapter

RF/coaxial connectors, such as SMA, are often found on test fixtures or on prototype board designs. Attaching a P7700 series probe to these on-board connectors is easy with the SMA adapter. The P77C292MM adapter allows you to connect to 2.92 mm, 3.5 mm or SMA connectors with full bandwidth and low noise. The P77C292MM adapter includes TriMode functionality enabling differential, single ended, and common mode measurements.

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
