Template:Plugin Sidebar 2 The Tektronix 7D01 is a logic analyzer plug-in for the 7000-series scopes. Compatible extension modules include the DF1 and DF2 display formatters and the DL2 latch (glitch detector). The 7D01 takes two P6451 8+1 channel probes.

Key Specifications

Channels	4 channels at 1016 bits/channel, maximum external clock period 10 ns (100 MHz) 8 channels at 508 bits/channel, maximum external clock period 20 ns (50 MHz) 16 channels at 254 bits/channel, maximum external clock period 40 ns (25 MHz)
Sampling Rate	10 ns to 5 ms per sample (1—2—5) or external clock up to 50 MHz
Trigger Sources	external channel 0 data 16 channel word recognizer manual

Notes

Note about external clock rates (from Jim Mauck):

When I was a Tek Service Technician I worked on the 7D01. For several years I tested every 7D01 I worked on (and that was a lot of them) with a 100 MHz external clock in 16 channel mode. I would use a DF2 and set it to reacquire continuously as long as the 7D01 memory was the same as the original data I stored into the DF2 memory. The analyzer would run for hours without error. The funny part is that it wasn't until I had been doing this for several years that I realized it wasn't specified to run at that frequency. I continued to test them that way even after I discovered my error. However the instrument exceeding the specifications might be due to the data source providing a generous setup and hold time relative to the active clock edge.
