[. . . ] Set A SEC/DIV to 10 I_LS, and A & B INT to CH 1 or CH 2 as appropriate for applied signal. Set A TRIGGER SLOPE for a positive-going signal (lever up) if the applied TV signal sync pulses are positivegoing, or for a negative-going signal (lever down) if the TV sync pulses are negative-going. OPERATOR' ADJUSTMENTS S INTRODUCTION Two adjustments should be performed before making measurements with your oscilloscope: Trace Rotation and Probe Compensation. Before proceeding with the following adjustment instructions, verify that the correct line fuse is installed (refer to the " Preparation for Use" information). Verify that the POWER switch is OFF (button out), then plug the power cord into the ac-power-input source. Push in the POWER switch (ON) and allow a 20-minute warm-up time before starting these adjustments. NOTE Normally, the resulting trace will be parallel to the center horizon tal graticule line, and the Trace Rotation adjustment should not be required. If the resulting trace is not parallel to the center horizontal graticule line, use a small flat-bit screwdriver to adjust the TRACE ROTATION control and align the trace with the center horizontal graticule line. PROBE COMPENSATION Misadjustment of probe compensation is one of the sources of measurement error. To ensure optimum measurement accuracy, always compensate the oscilloscope probe before making measurements. Pre set instrument controls and obta in a baseline er lnstrumen t Familiar izati on") . Use the Channel 1 POSITION control to move the baseline trace to the center horizontal graticule line. REV OCT 1981 15 2213 Operators 1. Preset instrument controls and obtain a baseline trace (refer to " Instrument Familiarization" ). CORRECT FLAT 2. Connect the two 10X probes (supplied with the instrument) to the CH 1 and CH 2 input connectors. Set both VOLTS/DIV switches to 0. 1 (10X PROBE) and set both AC-GND-DC switches to DC. Select CH 1 VERTICAL MODE and insert the tip of the Channel 1 probe in the PROBE ADJUST output jack. Using the approximately 1-kHz PROBE ADJUST square-wave signal as the input, obtain a display of the Instrument Familiarization" ). Set the SEC/DIV switch to display several cycles of the PROBE ADJUST signal. Check the waveform presentation for overshoot and rolloff (see Figure 10). If necessary, adjust the probe compensation for flat tops on the waveforms. Refer to the instructions supplied with the probe for details of compensation adjustment. Figure 10. Probe compensation. OVER COMPENSATED (OVERSHOOT) UNDER COMPENSATED (ROLLOFF) 465/DM-O-5 8. Select CH 2 VERTICAL MODE and connect the Channel 2 probe tip to the PROBE ADJUST output jack. Use the Channel 2 POSITION control to vertically center the display and repeat step 7 for the Channel 2 probe. BASIC APPLICATIONS After becoming familiar with all the capabilities of the 2213 Oscilloscope, the operator can then adopt a convenient method for making a particular measurement.
