Tek 1240/P6460

Jul 12, 2003 1 Replies

Hi all!



I recently bought a used Tektronix 1240 Logic analyzer including a set of P6460 pods. The manual for the analyzer was included, but does not seem to contain any information about the pods.



My question is:



What's the limits on input voltage to the pods?



My constructions tend to use 40xx series CMOS logic and usually has 9 or 12V power supply. Would it be safe to have 12 or even 15V input to the P6460, or do I have to construct and adapter. I have seen in the menus of the instrument that the threshold voltage can be set from -6.3 to +6.3V, so I assume it will accept voltages exceeding 5V.



With Best regards Leif Holmgren



The specs from the catalog are:

1MOhm, 5pF

-6.35V .. 6.35V threshold range

+/- 40V Maximum Input Voltage Peak +/- 60V Maximum Input Voltage Channel to Channel

The P6462 probe is more or less TTL only.
