Preface

This is the Technical Reference Manual for the TDP1500 differential probe. This manual provides specifications and
performance verification procedures for the probe.

Specifications

Specification

s

The specifications in Tables 1 through 4 apply to a TDP1500 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 on page 1.) The probe calibration routines should b e run on the host instrument before
verifying the warranted probe specifications. Specifications for the TDP1500 and differential probe fall into three categories:
warranted, typical, and nominal characteristics.
