The Tektronix Type 131 is a current probe amplifier used only with the P6016 current probe. Type 131s were never given serial numbers, instead, they were produced chronologically in "Models." Models 1 thru 3 looked alike, while Model 4 got a redesigned enclosure like that used later by the Type 134.
Key Specifications
| Sensitivity | 1 mA/Div to 1 A/Div, 1−2−5 (scope input fixed at 50 mV/Div) |
|---|---|
| Noise | 0.1 mAp-p |
| Risetime | 20 ns (eq. 17 MHz −3 dB bandwidth) |
| Lower frequency limit | 50 Hz |
| Delay time | 32 ns typ. |
(all specifications are overall values including the P6016 probe)
Connectors
All models of the 131 use a BNC input connector.
The vast majority of 131s, including all the Models 1 thru 3, have a UHF output connector. 131 Model 4s with UHF outputs were Tektronix #015-0029-00.
A few very late 131 Model 4s were supplied with a locking BNC output connector, as Tektronix #015-0050-00.
Internals
All four Type 131 models used PNP transistors, thus requiring a negative power source. Models 1 thru 3 were hard-wired to their separate minus ~19 V power supplies, while Model 4 got a power supply, 015-027, for 115 VAC, with a proprietary Tektronix coaxial connector. While the Type 134 uses the same coaxial power supply connector, the power supplies are not interchangeable — Type 131 Model 4 will only work with the correct 015-027 power supply.
See the 015-027 power supply page for more information.
