How to Operate Your Instrument
Bowtie Display
Pressing the
MAIN
button calls up the Main pop-up menu. From the Main pop-up menu, you can select the
Bowtie
display under the
Measure
heading. The Bowtie display evaluates the relative amplitude and timing between the three
video channels.
The Bowtie display requires a special test signal to be sent from the monitored source. The Tektronix TG2000 Signal
Generation Platform can produce an SD Bowtie test signal with 20 ns time marks, which aid in signal evaluation. The signal
is a 500 kHz sine wave on CH 1 (luminance) and 502 kHz sine waves on CH 2 (Pb) and CH 3 (Pr). For HD, the TG2000 can
produce an test signal with 1 ns markers. The signal is a 2.5 MHz sine wave on CH 1 (luminance) and 2.502 MHz sine
waves on CH 2 (Pb) and CH 3 (Pr).
Elements of the Bowtie display:
1. V Gain:
The vertical gain. Touch the
readout and use the knob to adjust.
2. H Gain:
Horizontal Gain. Touch the
