Fluke 80 - 50 MHz Function/Pulse Generators

80 Function generator

Model 80 provides Sweep and FM. In addition, the 80 offers linear and logarithmic sweep functions and external FM. This makes the 80 an extremely versatile low-cost function generator.

81 Pulse/function generator

With programmable pulse period, width, and transition times combined with the function generator features common to the 80 family, the 81 provides an impressive set of capabilities for both analog and digital applications.

Store common set-ups

Both the 80 and 81 stores 30 complete front panel setups, allowing easy recall of test set-ups.

Remote operation

Model 80 and 81 include an IEEE-488.2 (GPIB) interface as standard.

Autocalibration optimizes performance

Each Model has an autocalibration feature that allows the user to ensure maximum accuracy each time the unit is used.
