Just finished repairing a TDS460, and I'm trying to clear the error logs.
Sending ERR CLE or ERROR CLEAR via the GPIB, which works on the TDS5XX and
up scopes does not seem to work on the TDS4XX scopes. Wondering if anyone
knows how to clear the logs or what GPIB command is used? There's nothing
in the service or programmers manual about this.

Thanks.

Thanks Reinhard, but already been there - I've been an active member there
for a few years. Anyway, since I wasn't able to clear the error log via
GPIB, I disconnected the battery for a minute while the power was off. On
the first power up there was one power up failure on Dsp, and in the error
logs all of the previous errors were gone. On subsequent power ups, all is
well, except for the two errors that were generated from the loss of
Vbat. (NVRAM and Pudiag failure.)

I tried to set the dip switch 3 off hoping like the TDS5XX scopes that it
would skip these tests, but that didn't work either. Oh well, I guess I
can live with just the two errors
