Tektronix PG 508 50MHz Pulse Generator *Guaranteed*

This unit is fully operational and features the specs below: Unit is missing the sync gate/free run button, however a pen or something skinny can still activate the function perfectly. Period external, or internal <20 ns to >200 ms in 7 decade steps plus variable; ≥200 ms possible in custom range Jitter <0.1% +50 ps Delay Time <10 ns to >100 ms in 7 decade steps plus custom position and variable control; ≥100 ms possible in custom range Pulse Duration square, or <10 ns to >100 ms in 7 decade steps plus custom position and variable control; ≥100 ms possible in custom range Transition time Ranges 5 ns to 500 μs in decade steps plus custom position; separate  ×1 to ×100 variable controls for leading and trailing edge (5 ns to 50 ms effective) Output level High and low levels adjustable independently in −20 V to +20 V range, limited to max. 20 Vp-p / min. 1 Vp-p (open circuit), 50 Ω source impedance (−10 V to +10 V, 0.5 to 10 Vp-p into 50 Ω) Trigger/Gate input Sensitivity 80 mVp-p to ≥10 MHz, 250 mVp-p to ≥50 MHz at 50 Ω impedance, max. ±5 Vpeak; 1 MΩ // 20 pF optionally selectable (internal switch), max. ±20 Vpeak
