Auto Setup; Min Setup; Measurement System; Cursor Volts Measurements - Tektronix 2245A Operator's Manual

Pressing the AUTO SETUP button automatically sets up the front-panel
controls based on the characteristics of the applied signal. The voltage am­
plitude, sweep settings, trigger parameters, vertical and horizontal posi­
tioning, and trace intensities are preset to produce a usable waveform dis­
play. The waveform is horizontally centered and vertically positioned within
the crt display. The voltage and frequency characteristics of the input sig­
nal must be within the limits of the 2245A specifications given in Section 6.
Auto-setup action for each front-panel control is shown in Appendix A.
MIN SETUP is only available on instruments Serial Num­
bered B020100 or above.
Pressing and holding the Auto-Setup button until the instrument returns to
normal operation initiates the MIN SETUP function. This automatically sets
up the front-panel controls but leaves many of the controls unchanged from
what the user has set.
MIN SETUP action for each front-panel control is whown in Appendix A.

MEASUREMENT SYSTEM

The 2245A has a highly accurate voltage- and tim e- measurement system.
Voltage or time is measured between two cursors (or intensified zones for
time measurements in the ALT or B Horizontal MODE) that can be posi­
tioned, as desired, to two points on the waveform.

Cursor Volts Measurements

Press CURSOR VOLTS to display the voltage measurement cursors and
activate the voltage measurement system. The measured value is dis­
played at the top of the screen.
Changing the Horizontal MODE will remove the volts cur­
sors from the display. Set Horizontal MODE back to A or
X -Y and press the CURSOR VOLTS button to redisplay the
cursors.
