Deck 8: Signal Monitoring

Question 1

When analyzing the video signal on a waveform monitor, the view of the signal can be changed and certain parts enlarged.

Answer 1

True

Question 2

Active video when viewed as luminance only occupies the range between 7.5 and 1000 units or IRE.

Answer 2

False

Question 3

Because some of the color information on a normal color bar display would be beyond the waveform monitor's measuring limits, a color bar signal reduced to 75% of true levels is the general standard in use.

Answer 3

True

Question 4

The horizontal sync pulse should be at the -40 units line.

Question 5

The Low Pass filter on a waveform monitor (LPASS) selects the luminance portion of the signal only.

Question 6

Waveform monitors and vectorscopes are both measuring tools also known

A) oscillators
B) oscilloscopes
C) zoetropes
D) none of the above

Question 7

In front of the CRT of a scope is a glass or plastic plate made up of vertical and horizontal lines used to measure the video signal. This plate is called the

A) scale
B) face
C) target
D) graticule

Question 8

The scale on a waveform monitor that ranges from -40 to 100 IRE was referred to as how many volts of peak-to-peak video?

A) One
B) 1/1000
C) 3.58 volts
D) 100

Question 9

The horizontal line at zero units on a waveform monitor is referred to as the

A) zero line
B) base line
C) unit line
D) timing line

Question 10

The horizontal line at zero units is marked with vertical divisions in

A) milliseconds
B) microseconds
C) tenths of microseconds
D) both B and C
