Autorange on (Fig. 32):
•
Time/div and Volt/div settings are displayed inverted
•
The time base and input sensitivity are automatically set for
optimal viewing of the input signal.
•
Auto-triggering is set for time base 2µs/div or slower,
(HPS10 : 5µs/div)
•
Normal triggering is set for time base faster then 2µs/div.
(HPS10 : 5µs/div)
•
The slowest possible time base is 5ms/div.
•
The fastest possible time base is 250ns/div, (HPS10 :
1µs/div)
•
Y-position is set to the center location.
Autorange off (Fig. 33) :
•
Time/div and Volt/div settings are displayed in a normal font (not inverted)
•
Cursor keys are set for changing the time base and input sensitivity.
G
Note:
Changing the time base, input sensitivity, Y-pos or trigger mode turns
off the auto range-mode.
CHANGING THE INPUT SENSITIVITY AND TIMEBASE
First press the „t-V/div“ key Use up/down cursorkeys for changing the input sensitivity (V/div) (Fig 34)
Press the left/right cursorkeys for changing the timebase (time/div). (Fig 35)
1. Changing Volt/div:
The signal on the screen can be enlarge or reduce vertically by adjusting the displayed voltage per division. (V/div =
voltage per division). The divisions can be made visible through the Display set-up key (see display setup).
Select the sensitivity: from 5mV to a maximum of 20V per division.
F
50mV to 200V with X10 probe selection
Pressing the up cursor key increases the input sensitivity (lower value for V/div).
Pressing the down cursor key decreases the input sensitivity (higher value for V/div).
2. Changing the timebase:
Adjusting the time base will visualize more or fewer periods of a signal (t/div = time per division). The
divisions can be visualized through the Display set-up key (see display setup). Set the time base
between 1h and 50ns per division. (1h to 0,2µs for HPS10)
Press the ‘t-V/div’-key to set the cursorkeys action into ‘timebase’ mode.
Press the ‘left’ or ‘right’ cursor keys to increase or decrease the timebase (time/div).
