Trace Rotation Adjustment; Probe Low-Frequency Compensation - Tektronix 2245A Operator's Manual

2. Set:
VERTICAL MODE
Horizontal MODE
3. Press the AUTO SETUP
Normally, the Auto Setup of the display Is sufficient for
measurement purposes. If further waveform enhancement
is needed, use the appropriate front-panel controls to
adjust the display. For auto-setup action, see Appendix A.

Trace Rotation Adjustment

1. Perform the " Initial Setup" procedure. Position the trace vertically to
align it with the center horizontal graticule line and check that the trace
is parallel with the graticule line.
Normally, the trace will be parallel to the center horizontal
graticule line, and the TRACE ROTATION adjustment will
not be needed.
2. If necessary, adjust the TRACE ROTATION to make the baseline trace
parallel to the center horizontal graticule line. Use a small straight-blade
screwdriver or alignment tool.

Probe Low-Frequency Compensation

Misadjustment of probe compensation is a possible source of measurement
error. The attenuator probes are equipped with compensation adjustments.
To ensure the best measurement accuracy, always check probe compen­
sation before making measurements.
1. Connect the two supplied 10X probes to the CH 1 and CH 2 BNC input
connectors.
