Tektronix P6046

100 MHz differential probe

Compatible with 50 Ω scope inputs

Produced from 1968 to 1992

Manuals

There are three versions of the manual:

070-0756-00 - 1968 − assumes 1A5 for absolute gain calibration
070-7129-00 - 1988
070-7129-01 - 1992

The Tektronix P6046 is a 100 MHz differential probe oscilloscope probe introduced in 1968 and discontinued sometime after 1992. It was designed by Glenn Bateman.

It was initially intended for use with a 1A5 plug-in, to which it attaches through a 9-pin Amphenol 165 series connector.

A separate amplifier (015-0106-00) was available as an option to use the probe on a 50 Ω input scope set at 10 mV/Div.

An additional ×10 attenuator (010-0361-00) can be plugged onto the P6046's inputs.

Note that the probe itself acts as either a 1× or 10× attenuation probe dependent on a signal voltage on pin D of the connector. When used with the amplifier, 10× mode is used in the 200, 100, and 50 mV/div settings and 1× mode for 20, 10, 5, 2, and 1 mV/div.

Key Specifications

Bandwidth	45 MHz with 1A5; 100 MHz with amplifier; AC low frequency cut-off 20 Hz (2 Hz with ×10 head)
Input impedance	1 MΩ // 10 pF (with ×10 head, 10 MΩ // 3 pF)
Common-mode range	±5 V DC+peak AC up to 10 MHz, decreasing to ±2 V at 50 MHz
Maximum Allowable Input	25 V total DC+peak AC, 25 V total difference between + and − input tips

Operation

The two probe tips are (in DC mode) directly connected to the gates of a pair of JFETs.

Use the shorting plugs on the tips when not in use:

Ground the probe! Seriously. Sticker the probe "Ground Me!" I also recommend stickering the probe amplifier with the ATTEN BAL setup procedure from section 2-6 of the manual.
