Chapter 4

Calibration Procedure

The 346B Synthesized Calibrator is packaged on a single, printed circuit board. All
the adjustments are accessible from the top of the unit with the top cover
removed.

Test Equipment

Note: Equivalent equipment can be substituted.

Digital Multimeter

Keithley 191

Voltage to Charge Converter

Trig-Tek 2030

Charge Amplifier

Trig-Tek 203M

Distortion Analyzer

Hewlett Packard 334A

Procedure

Before turning on the unit, check the 115-230 VAC switch S1,

Figure 4-1,

near the

transformer for proper setting to accommodate the power to be used. Connect
the power cord to AC power and place the ON-OFF switch to ON.
