Established in 1990, Fadong Power Co., Ltd. is a professional China timing generator manufacturer and supplier of in the emergency power supply industry. We not only specialize in manufacturing different kinds of generators, but also in motors, engines, diesels, gearmotors and other power supply products. We also have more than 100 series of equipment to support and check our products, such as VPI equipment, auto painting lines, auto testing systems and CAD systems. We warmly welcome every customer to cooperate with us on the basis of mutual benefit, and hope to be your faithful friend and best partner. Our custom timing generators has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS.

HP 59308A Timing Generator
The 59308A Timing Generator provides pacing and timing signals output for remote use via the Interface Bus, or on rear panel BNC
Rear panel BNCs output TTL and ECL levels with switch selection of square wave or pulse, and of positive going or negative-going edge
Output pulses are 500 ns ±100 ns wide, rise time of 50 ns
It has two output ranges with maximums of 9V or 99V, and the DS3 has four overlapping decade ranges providing maximums of 32 μA, 320 μA, 3.2 mA , and 32 mA. All ranges are continuously adjustable by a calibrated multi-turn output control and the polarity of the output can be reversed by a toggle switch.
Current is drawn from the batteries only when delivering an output pulse, minimizing the drain on them. The maximum current drain is 30 mA plus the load current. These instruments have nonconductive enclosures and may be mounted on a metal mounting frame without connecting the internal circuits to ground. A single shot button is provided which can be operated at all times irrespective of the trigger input.

Designed for control of normal repetitive stimulation as well as for defining the Effective Refractory Period using a second, delayed pulse.
Trigger timing generator
Ideal for electrophysiology
Perfect match for DS2A and DS7A Stimulators
Internal battery
The DG2A Train Delay Generator is an ideal instrument for electrophysiological recordings requiring pulsed stimulation of samples. It is especially useful for use with our DS2A Isolated Stimulator which has its own pulse width control.
The unit features Rate/Frequency control spanning 3 full decades, and selection of single or twin pulses with 3 decade control of the inter-pulse delay. A single shot button is fitted to supply pulses on demand (when the oscillator is off) or in addition to the repetitive stimuli (when the oscillator is on). The oscillator (frequency generator) can be switched to free-run, off, or on while the switch is held.
A SYNC output socket is available for triggering recording devices. The OUT output can be selected as either the non-delayed pulse, the delayed pulse, or both (twin) pulses.
The instrument is powered by an internal 9 volt battery (PP3 - 6R61 style), but can also be powered by an external calculator-style plug-in power supply (not supplied).
