''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.'' | ''When I was a Tek Service Technician I worked on the 7D01.

The 7D01 is often affected by [[bad TI IC sockets]], see [[7D01/Repairs|the Repairs tab]]. | |||
