TA1360AFG

Note Characteristics

HB01 H-OUT pulse duty

Test Conditions

1. No signal input.

2. Measure T1 and T2 (as shown in the figure below) from #37 (H-OUT) output waveform when

subaddress (00) data is 80H and A0H. Calculate duties (THA and THB) using the following

equation:

TH = T1/(T1 + T2) Ã 100 %

#37 waveform

HB02 Horizontal free-run

frequency

1. Set SW44 to open.

2. Set subaddress (00) data to 01H and measure horizontal free-run frequency (F15K) according

to #37 (H-OUT) output waveform.

3. Set subaddress (00) data to 00H, 41H, 81H, C0H, and C1H. Measure horizontal free-run

frequency F28K, F31K, F33K, F37K, and F45K as in the step 2 above.

HB03 Horizontal oscillation 1. Set subaddress (00) data to 01H.

frequency variable

range

2. Connect 10-kâ¦ resistor between #44 and VCC. Measure horizontal frequency (F15KMIN)

according to #37 (H-OUT) output waveform.

3. Connect 68-kâ¦ resistor between #44 and GND. Measure horizontal frequency (F15KMAX)

according to #37 (H-OUT) output waveform.

4. Set subaddress (00) data to 00H, 41H, 81H, C0H, and C1H. Repeat the steps 2 and 3 above

and measure horizontal frequencies F28KMIN, F28KMAX, F31KMIN, F31KMAX, F33KMIN,

F33KMAX, F37KMIN, F37KMAX, F45KMIN, and F45KMAX.

HB04 Horizontal oscillation 1. Set SW44 to open.

control sensitivity

2. Connect external power supply to TP44, and set subaddress (00) data to 01H.

3. Apply V44 + 0.05 V, and V44 â 0.05 V to TP44. Measure frequencies FA and FB according to

#37 (H-OUT) output waveform. Calculate frequency change rate (BH15K) using the following

equation.

BH15K = (FB â FA)/0.1

4. Set subaddress (00) data to 00H, 41H, 81H, C0H, and C1H. Repeat the step 2 above, and

measure frequency change rate BH28K, BH31K, BH33K, BH37K, and BH45K

HB05 H-OUT output

voltage

1. Set SW37 to open.

2. Measure voltage at High (V37H) and Low (V37L) of #37 (H-OUT) output waveform.
