CMRR: At least 10:1 at 50 MHz.
Input R and C: 1 MΩ, 20 pF.
Max Input Voltage: 400 V (dc +peak ac) or 800 Vp-p.
Channel Isolation: 50:1 at 100 MHz.
HORIZONTAL SYSTEM
Sweep Speeds: A Time Base: 0.5 s/div to 20 ns/div; B Time Base: 5 ms/div to 20 ns/div (X10 MAG to 2 ns/div A and B)

Horizontal Operating Modes: A, ALT, B, X-Y.
Delay Jitter: 20,000:1.
Delay Accuracy: ±0.5% + 5% of one div +25 ns.
TRIGGER SYSTEM
Trigger Sensitivity (A and B)- dc: 0.35 div to 25 MHz, 1.0 div at 150 MHz. Noise Reject: 1.4 div to 25 MHz, 2.2 div at 100 MHz.
HF Reject: attenuates above 70 kHz. LF Reject: attenuates below 50 kHz. ac: Same as dc, attenuates below 25 Hz. TV Line, TV Field: 0.5 div of composite sync for stable display.Trigger Operating Modes: A mode: AUTO LEVEL, AUTO, NORM, TV LINE, TV FIELD, SINGLE SEG. B mode: RUNS AFTER DELAY, AUTO LEVEL, NORM, TV LINE (from A source).
Trigger Source (A and B): VERT, CH 1, 2, 3, 4, LINE.
Variable Holdoff: At least 10:1.
X-Y OPERATION
Deflection Factors: Same as vertical system.
X-Y Operating Modes: X: CH 1; Y: CH 1, 2, 3, 4, and ADD
Bandwidth: X-Axis: 3 MHz; Y-Axis same as vertical System.
Phase Difference: ±3° from dc to 50 kHz.
CRT SYSTEM
