The GenRad 1539-A Stroboslave is a stroboscope light source that satisfies the basic requirements for motion studies and high-speed photography. It is suit
able for all stroboscope applications except tachometry. More than one Stroboslave can be used where there is a need for multiple light sources. When the reflector is removed from the end of the extension cord, the strobotron lamp assembly can be inserted through a hole as small as one inch, making it possible to observe objects in otherwise inaccessible areas.

The 1539-A Stroboslave is a miniature electronic stroboscope without an internal oscillator for setting the flashing rate: hence, its inability to function as a
tachometer. It will operate directly from a switch closure, a Type 1537-A Photoelectric Pickoff, a Type 1531-P2 Flash Delay (with a Type 1536-A Photo
electric Pickoff), or an electrical positive pulse of at least 2 volts peak. In addition, it will operate directly from the output, of the GenRad 1531, 1538 or 1546
The Stroboslave produces the same light output as the Type 1531-A Strobotac and operates over the same three basic ranges from 0 to 25,000 flashes per minute.The strobotron lamp and reflector are connected to the unit by a five-foot flexible cable so that the light can be positioned close to the subject to be observed.
