SCD1000
The Tektronix SCD1000 is a transient digitizer based on a scan converter tube. It is similar to the SCD5000, but the SCD1000 has a vertical amplifier instead of direct access. Because of this, the SCD1000 has 100 mV full-scale sensitivity, 50 times more sensitive than the SCD5000. However, the SCD1000 has only 1 GHz vertical bandwidth instead of the SCD5000's 4.5 GHz.
The vertical amplifier uses the 7104's 155-0174-00 delay line compensator, 155-0175-00 trigger amplifier and 155-0176-00 vertical output amplifier, all in Hypcon packages.
