5–3
7. Variable Autotransformer
For example:
General Radio Metered Auto Transformer W10MT3W. If 220 V operation
must be checked, a conversion transformer or appropriate 220 V autotrans-
former is needed.
8. Voltmeter
Range: 0 to 100 Vdc. Accuracy: 0.1%.
For example:
Tektronix DM501A installed in a TM500–Series Power Module.
9. Video Amplitude Calibrator (VAC)
Signal: Adjustable square wave 0.0 to 999.9 mV p-p. Resolution: 0.1 mV.
Accuracy: 0.05%. Frequency: Approximately 270 Hz.
For example:
Tektronix 067-0916-00 installed in a TM500–Series Power Module.
10. Peak-to-Peak Detector
Input Signal Range: 0.25 to 1.0 V p-p. Flatness: 0.2% 50 kHz to 10 MHz.
Input Impedance: 75 .
For example:
Tektronix Part No. 015-0408-00 (includes Peak-to-Peak Detector Head
015-0413-00) installed in a TM500–Series Power Module.
11. Power Module
For powering and housing Tektronix SG505, FG503, DM501A, DC503A,
067-0916-00, and a 015-0408-00.
For example:
Tektronix TM500–Series Power Module.
12. Low-Distortion Oscillator
1-kHz balanced output, 387 mV to 1.54 V amplitude.
For example:
Tektronix SG505 Opt. 2.
