    Section 1 general description 1.1 the model 801 double pulse controlled by delay control. Double pulse at all outputs except sync. The model 801 is a 50 mhz general purpose laboratory pulse generator. The instrument gives you full control in primary pulse triggering and shaping plus simultaneous ttl...

    Fixed (ecl, ecl, ttl) pulses pulse levels for loading as shown: ecl -0.9v delay pulse occurrence can be delayed from less than 10 ns to 100 ms with respect to the sync pulse. Maximum duty cycle is 70% for periods to 200 ns, decreasing to 30% for 20 ns periods. Delay jitter is less than 0.1% plus 50 ...

    Respect to its sync pulse. These pulse parameters are shown in figure 3-2. Specific setups for each mode are given in paragraph 3.3. 3.2.1 white marks when first becoming familiar with the 801, the white mark settings are handy. The white mark settings for the front panel switches will always give a...

    The output norm/comp switch could also be used to reverse the upper and lower levels as the trigger edge does, but some error could be introduced by the x-y multiplier.
