2T Pulse to Bar. 2T pulse-to-bar measurements are made using the solid and
dashed lines located to the left of the K-Factor graticule. Setup is the same as for
K-Factor measurement. The 2T pulse-to-bar graticule lines are scaled according
to the following formula:
1 and 1
(1–4K) (1+4K)
Where:
K = 0.02 for 2% K Factor (using the dashed lines)
or
K = 0.04 for 4% K Factor (using the solid lines)
Set Gain to X5 to increase the resolution to 0.4% and 0.8%.
The horizontal reference line (0 V) is also referred to as the base line, 0 mV,
blanking level, and black level. The reference line has 12 major divisions. Main
marks at the 1st, 6th, and 11th divisions provide for timing and linearity
measurements, which should occur within the center ten divisions. When the
Sweep button is set to 1-Line, each major division represents 5 ms, and when set
to 2-Line sweep, each major division represents 10 ms. The current deflection
factor is displayed in the upper-right corner of the CRT.
Pressing the MAG button magnifies the sweep so the scale on the baseline equals
500 ns per major division for 1-Line sweep and 1 ms per major division in 2-Line
sweep. Use the HORIZ POS knob to view the waveform extremes when
magnified.
