The Fluke Model 5800A Oscilloscope Calibrator (Figure 1-1) is a precise instrument that calibrates analog and digital oscilloscopes. Features of the 5800A Calibrator include the following: · Automatic meter error calculation. · X and D keys that change the output value to pre-determined cardinal values for various functions. · Programmable entry limits that prevent invalid amounts from being entered. · Edge, Leveled Sine, Pulse, Marker, and Wave Generation modes. · Accurate oscilloscopic input impedance measurement. · Tunnel Diode Pulse compatibility. · External reference. · Auxiliary input. · 5-channel output (5-channel option). The 5-channel option allows you to calibrate up to five oscilloscope channels simultaneously without changing cables. · Simultaneous output of a signal and a trigger signal. · 600 MHz, Leveled Sine wave output. · Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1-1987 and 488.2-1987. · EIA Standard RS-232-C serial data interface for printing, displaying, or transferring internally stored calibration constants, and for remote control of the 5800A. · Pass-through RS-232-C serial data interface for communicating with the Unit Under Test (UUT). · Extensive automatic internal self testing and diagnostics of analog and digital functions.
