s
The specifications in Tables 1 through 4 apply to a TDP0500 or TDP1000 differential probe installed on a Tektronix DPO7000
oscilloscope. When the probe is used with another oscilloscope, the oscilloscope must have an input impedance of 50 Ω
and a bandwidth of 1 GHz. The probe must have a warm-up period of at least 20 minutes and be in an environment that
does not exceed the limits described. (See Table 1.) The probe calibration and Autozero routines should be run on the host
instrument before verifying the warranted probe specifications. Specifications for the TDP0500 and TDP1000 differential
probes fall into three categories: warranted, typical, and nominal characteristics.

This section describes the characteristics of the adapters that are included in your accessory kit. The adapters are listed
in order of performance, beginning with the fastest. You will get the best probe performance by connecting the probe
directly to square pins on y our circuit. However, as test points are not always as convenient, these adapters make taking
measurements easier while maintaining the best signal fidelity.
NOTE. All adapter specifications are typical unless otherwise indicated.

Rise Time
This procedure verifies that the probe meets the warranted 4.25 V range rise time specification. Two rise times are
measured; the test system alone, and then the test system with the probe included. The probe rise time is calculated
using the two measurements.
This test uses the TDR function of the 80E04 sampling head as a fast rise time signal source. A second 80E0X sampling head
is used to take the measurements. Although the following procedure assigns the TDR and measurement functions to specific
oscilloscope channels, any channels can be used. However, the TDR function is only available on 80E04 sampling heads.
CAUTION. To prevent damage, use care when working with SMA connectors: support equipment to avoid mechanical strain
on the connectors, and when tightening connections, use a torque wrench to 7.5 in-lbs.
