[. . . ] Perform Step 1 under Displaying a TV Line-rate Signal. 2. Set A SEC/DIV to 2 ms, A TRIGGER MODE to TV FIELD and A & B INT to CH 1 or CH 2 as appropriate for the applied signal. Perform Step 3 and 4 under Displaying a TV Line-rate Signal. To display either Field 1 or Field 2 individually at faster sweep rates (displays of less than one full field), set VERTICAL MODE to BOTH and ALT simultaneously. This synchronizes the Channel 1 display to one field and the Channel 2 display to the other field. To change the field that is displayed, interrupt the triggering by repeatedly setting the AC GND DC switch to GND or disconnecting the signal from the applied signal input until the other field is displayed. To display both fields simultaneously, apply the input signal to both the CH 1 and CH 2 inputs via two probes, two cables, or through a dual-input coupler. To examine either a TV Field-rate or Line-rate signal in more detail, either the X10 Magnifier or HORIZONTAL MODE functions may be employed as described for other signals elsewhere in this manual. TV SIGNAL DISPLAYS Displaying a TV Line-rate Signal 1. Perform the steps and set the controls as outlined under Baseline Trace and Signal Display to obtain a basic display of the desired TV signal. 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. Most attenuator probes are equipped with compensation adjustment. To ensure optimum measurement accuracy, always compensate the oscilloscope probe before making measurements. Probe compensation is accomplished as follows: TRACE ROTATION -1.
