[Jean-Guy Michaud]

My Tek 475A has a 155-0217-00 IC in the trigger preamplifier circuit =
(U520, U720). However, the manual I have specifies a 155-0032-01 for =
this function.=20

Is the 0217 a newer replacement for the 0032?=20

Also, is the trigger calibration procedure the same for both ICs?=20

Thank you,=20
