General Information
Table 1-3.
INPUT CHANNELS A AND B
Range:
dc coupled: 0-50 MHz
ac coupled: 20 Hz - 50 MHz
Sensitivity:
0.1 V rms sine wave
0.3 V p-p pulse
8 ns minimum pulse width
Sensitivity can be decreased by 10 or 100
times, using the ATTENUATOR switch.
Impedance: 1 MO shunted by less than 25 pF
Dynamic Input Voltage Range:
0.1 to 3 V rms ac times attenuator setting
±5 Vdc times attenuator setting.
Trigger Level:
PRESET to center triggering about 0 V or
variable over the range of -3 V to +3 V times
attenuator setting. Trigger threshold band
<1.0 mV, referred to input at maximum
frequency.
Overload Protection:
250 V rms on all attenuator settings, except
25 V rms on XI above 50 kHz.
Slope:
Independent selection of positive or negative
slope.
Channel Inputs: Common or separate lines.
Marker Outputs:
Rear panel BNC’s DTL pulse, low for
approximately 2 ps after trigger point for A
and B channels.
INPUT CHANNEL C

Range:
direct: 1 kHz - 50 MHz, ac coupled
prescaled: 0-550 MHz, dc coupled
Sensitivity:
direct: 5 mV rms
prescaled: 100 mV rms
Impedance: 500 nominal
Maximum input: 5 volts rms; 7.5 volts peak
Trigger Level: 0 volts
5326A
Range: 0 to 50 MHz, dc coupled
