455/A2/B2
VOLTAGE CONDITIONS
Voltages shown on this schematic diagram were measured with a Tektronix DM 501 Digital Multimeter. Voltage measurements can vary as
much as +20%.
No signals were applied to the Vertical or Horizontal modules. The 455 INTENSITY control was set to midrange.
WAVEFORM CONDITIONS
Waveforms below were taken from a Tektronix 7000-Series oscilloscope equipped with readout, 7B series Time-Base, 7A13 Differential
Comparator and a 10X probe. The offset voltages were read directly from the 7A13 in the dc coupled mode. If a different test oscil
loscope system is used, the ac coupled mode may have to be used due to high dc offset voltages. This can cause some waveforms to appear
slightly different. Waveforms may vary as much as ±20%.
The 455 INTENSITY control was set to midrange. The Horizontal Module (A) sweep was free-running. A INTEN mode was used with
delaying sweep module (B2). See note on waveforms.
Waveforms 3, 4, 5, 6 and 7 were taken using waveform at TP522 to externally trigger the test oscilloscope.
