1-2. Technical Specifications
 INPUT A CHARACTERISTICS
• FREQUENCY RANGE : 0.1 Hz to 100 MHz (DC Coupled)
30 Hz to 100 MHz (AC Coupled)
• SENSITIVITY : 0.1 Hz to 1 Hz: 250 mV
1 Hz to 100 MHz: 30 mV
• COUPLING : AC or DC Selectable
• IMPEDANCE : 1 MΩ Resistance, Shunted by < 40 pF
• ATTENUATOR : x 1 or x 10 Switch Selectable
• LOW PASS FILTER : -3 dB Point of 100 kHz, Switch Selectable
• TRIGGER LEVEL : + 350 mV to – 350 mV (PRESET 0 V)
• SLOPE : Positive or Negative Slope Switch Selectable
* NOTE: Trigger error is typically ±0.3 % of reading by the number of cycles
averaged for input signals having better than 40 dB S/N ratio and greater than
100 mV amplitude.
