Tektronix 502A User Manual

Operating Instructions — Type 502A
Fig. 2-2. The power transformer has two extra windings permitting nominal primary voltages of 110, 117, 124, 220, 234 or 248 volts, 50
or 60 cycle operation.
Fan Connections
The manner in which the fan is wired depends on the line
voltage. For 110-124 or 220-248 volt operation, the fan is
connected as shown in Fig. 2-3.
Fuse Requirements
Use a 4 amp., 3AG, Fast-Bio fuse for 110, 117 or 124 volt
60 cycle operation; for 50 cycles use a 3.2 amp., 3AG, S l o-
B l o fuse. For 220, 234 or 248 volt, 60 cycle operation, use
a 2 amp., 3AG, Fast-Bio fuse; for 50 cycles use a 1.6 amp.,
3AG, S l o-B l o fuse.
Input Selection
On the Type 502A oscilloscope, you can connect single-
ended inputs to either the A or B input connectors of the
LOWER or UPPER BEAM amplifiers by rotating the Input
Selector switches to the corresponding position. The choice
of input connections will depend upon the display desired.
Waveforms applied to input B are displayed in an inverted
position on the face of the crt while waveforms applied to
input A are displayed in the normal upright position. If
you are not aware of this difference in the input connectors,
it is probable that you will improperly evaluate the results
obtained from an input to the B connector.
