    Deflection Factor and Accuracy: CH 1&2: 2 mV/ div to 5 V/div; CH 3&4: 0.1 V/div and 0.5 V/div; all at ±2% (±3% outside +15°C to +35°C). CH 1&2 variable at least 2.5:1

    Vertical Operating Modes: CH 1, 2, 3, 4, CH 2 INVERT, ADD, ALT, CHOP (625 kHz).

    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)
    Accuracy: ±2%; Magnified ±3% (degrade by 1% outside +15°C to +35°C).
    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
