Thurlby Thandar Instruments TGP110 10 MHz Pulse Generator

The Thurlby Thandar Instruments TGP110 is a 10 MHz analog pulse generator delivering precise control over pulse parameters from 0.1 Hz to 10 MHz. It generates pulses with independently adjustable width, delay, and period, each spanning 50 ns to 5 s with <0.1% jitter. The instrument provides two switch-selectable output amplitude ranges (0.1–1.0 V and 1–10 V) into 50 Ω impedance, with rise/fall times typically 10 ns and aberrations <5%.

Auxiliary CMOS/TTL and sync outputs support timing-critical applications. Operation in continuous or externally triggered mode enables flexible test configurations; trigger input accepts DC to 10 MHz signals at TTL threshold with ±10 V maximum range. Housed in a compact benchtop format, the TGP110 operates from 110–240 V AC (internally selectable) at 50/60 Hz and meets EN61010-1 Safety Class I and EN61326 EMC standards.
