PeakTech 2020 GN User Manual

2.1.1 Display and Power Blocks
(16) POWER switch
Push into turn instrument power on and off.
(16-1) POWER lamp
Sights when power is on
(2) INTEN control
Adjusts the brightness of the CRT display. Clockwise rotation increases brightness.
(1) FOCUS control
To obtain maximum trace sharpness.
(29) Rotation control
Allows screwdriver adjustment of trace alignment with regard to the horizontal gratitude lines of CRT.
(32) Fuse holder
(33) Voltage Selector
Permits changing the operating voltage range
(34) Power Connector
Permits removal or replacement of the AC power cord.
2.1.2 Vertical Amplifier Block
(24) CH1 or X IN connector
For applying an input signal to vertical amplifier channel 1, or to the X-axis (horizontal) amplifier
during X-Y operation.
Caution:
To avoid damage to the oscilloscope, do not apply more than 400 V (DC + Peak AC) between
"CH1" terminal and ground.
(22) CH2 or Y IN connector
For applying an input signal to vertical amplifier channel 2, or to the Y-axis (vertical) amplifier during
X-Y operation.
Caution:
To avoid damage to the oscilloscope, do not apply more than 400 V (DC + Peak AC) between "CH"
terminal and ground.
(25) CH1 AC/GND/DC switch
To select the method of coupling the input signal to the CH 1 vertical amplifier. AC position inserts a
capacitor between the input connector and amplifier to block any DC component in the input signal.
GND position connects the amplifier to ground instead of the input connector, so a ground reference
can be established.
DC position connects the amplifier directly to its input connector, thus passing all signal components
onto the amplifier
(21) CH 2 AC/GND/DC switch
To select the method of coupling the input signal to the CH 2 vertical amplifier.
(26) CH 1 VOLTS/DIV switch
To select the calibrated deflection factor of the input signal fed to the CH 1 vertical amplifier.
(23) CH 2 VOLTS/DIV switch
To select the calibrated deflection factor of the input signal fed to the CH 2 vertical amplifier.
(27)+ VARIABLE controls
(20) Provide continuously variable adjustment of deflection factor between steps of the VOLTS/DIV
switches.
