Characteristics
Performance Requirements
HORIZONTAL DEFLECTION SYSTEM (cont)
Delay Time Position Range
0 to 9.95 times the A SEC/DIV switch setting. Main sweep triggering
event is observable on delayed sweep with zero delay setting.
X-Y Operation
X-Axis Deflection Factor
Range
Same as Channel 1.
Accuracy
Same as Channel 1.
Variable Range
Same as Channel 1.
X-Axis Bandwidth
Dc to 3 MHz.
Input R and C
Same as Channel 1.
Phase Difference Between X and Y with Normal
Bandwidth
1° or less from dc to 1 MHz;
3° or less from 1 MHz to 2 MHz.
X-Axis Low-Frequency Linearity
0.2 division or less compression or expansion of a two-division,
center-screen signal when positioned within the display area.
CURSOR AND FRONT-PANEL DISPLAY
Cursor Position Range
Delta Volts (AV)
At least the center 7.6 vertical divisions.
Delta Time (At)
At least the center 9.6 horizontal divisions.
Minimum Setup Time Required to Maintain
Front-panel Settings at Power-down
10 seconds or less.
Z-AXIS INPUT
Sensitivity
Positive voltage decreases intensity. From dc to 2 MHz, +2 V blanks
a maximum-intensity trace; from 2 MHz to 20 MHz, +2 V modulates
a normal-intensity trace.
Input Resistance
10 k ft ±10%.
Maximum Input Voltage ^
±25 V peak; 25 V p-p ac at 10 kHz or less.
SIGNAL OUTPUTS
CALIBRATOR
Output Voltage and Current
0.4 V ±1% into a 1-M£2 load, 0.2 V ±1.5% into a 50-£2 load, or
8 mA ±1.5% into a short circuit, with the A SEC/DIV switch set to
1 ms per division.
Repetition Period
Two times the A SEC/DIV switch setting within the range of 200 ns
to 200 ms.
Accuracy
±0.1%, measured with SGL SEQ A TRIGGER MODE selected.
