Tektronix 47E5A

Accuracy for Measurements Less than One Major Dial
Division: Within ±0.01 major dial divisions from +15 ° C to
+35°C. Within ± 0. 02 major dial divisions from -15°C to
+55 ° C.
DIFFERENTIAL TIME
MEASUREMENT (DM44)
Refer to TIME AND 1/TIME under DM44 DIGITAL
MUL TIMETER .
HORIZONTAL
Sweep Rate Accuracy: Within 2% , unmagnified , and 3%
magnified, from +20 °C to +30°C for A and 8 Sweeps.
Mixed Sweep Accuracy: With in 2% plus the measured A
Sweep inaccuracy, when viewing the A portion only. 8
Sweep portion remains the same as above.
Trigger Holdoff Variable: Increases A S'weep holdoff
time by at least a factor of 10.
Delay Time Jitter: 1 part, or less, in 50,000 (0.002%) of
10 times the A TIME/DIV switch setting .
Calibrated Delay Time (VAR control to CAL):
Continuous from 0.2 ps to at least 5 seconds after the start
of A (delaying) sweep.
x-v
X-Axis Sensitivity (X10 MAG turned off): Same as the
vertical system.
X-Axis
Bandwidth : Dc to at least 4 MHz , with a
10 division reference signal.
Phase Difference Between X- and V-Axis Amplifiers:
Within 3° from dc to 50 kHz.
Deflection Accuracy: Within 4%.
CALIBRATOR
Output Voltage: 0.3 V within 1% and within 0.3% from
+20°C to +30°C.
Output Current: 30 mA within 2% from +20 °C to
+30°C.
Repetition Rate: About 1 kHz.
