A slide switch under the right side cover allows the variable sweep control to be used as a variable holdoff control instead. | |||
The SC504 uses some custom Tek ICs, namely the [[155-0124-00]] preamplifier (U4345), [[155-0109-01]] trigger (U3238), and [[155-0122-00]] A-B logic (U3158). There are two passive input attenuator hybrids (HY1520, HY1420) and two [[155-0161-00]] attenuator/amplifier hybrids (HY1530, HY1430). | The SC504 uses some custom Tek ICs, namely the [[155-0124-00]] preamplifier (U4345), [[155-0109-01]] trigger (U3238), and [[155-0122-00]] A-B logic (U3158).
