Notes

The Tektronix 7B15 is a 1 GHz delaying time base for 7000-series scopes, in particular, the 1 GHz 7104 (typically used with 7A29 vertical amplifiers and a 7B10 delayed time base).

The 7B15 provides digital readout of delay and delta times. In effect, the 7B15/7B10 pair are speed-improved versions of the 7B85/7B80.

Specifications

Sweep200 ms/Div to 2 ns/Div in 1-2-5 sequence, ×10 magnifier down to 200 ps/Div, variable to ×2.5
Triggeringto 1 GHz
Jitterless than 30 ps at 1 GHz
Features
  • Digital read-out of delay and delta times
  • Variable Trigger Holdoff
  • HF Sync mode

Internals

A ramp generator is started when the trigger signal arrives. The delayed sweep is started when a comparator detects that the ramp has reached a control voltage, set by the front panel knobs. The control voltage is therefore proportional to the amount of delay and is measured using a 155-0185-00 4-digit DVM circuit, then displayed on the oscilloscope readout. The display, scaled in seconds, provides the operator with a precise readout of the delay.

Other custom Tek ICs used: 155-0150-00 trigger detector, 155-0160-00 trigger amplifier.

The 7B15 uses the +50 V supply provided by the mainframe.
