Table 1-1: Input characteristics, channels A and B (cont.)
Characteristic
Description
9 Trigger Level Uncertainty,
1X
±(15 mV + 1% of trigger level)
TLU for uncertainty analysis purposes
9Trigger Level Uncertainty,
10X
±(150 mV + 1% of trigger level)
Tested as part of Trigger Level Uncertainty (1X)
AUTO Trigger Level Trigger level is automatically set to 50% point of input signal (10% and 90% for Rise/Fall Time)
AUTO Hysteresis, Time Minimum hysteresis window (hysteresis compensation)
AUTO Hysteresis, F requency One third of input signal level
Instrument measures Signal(high) + N oise(pk) - ½ hysteresis and Signal(low) – Noise(pk) + ½
hysteresis to calculate 30% and 70% levels for auto-hysteresis
Analog LP Filter
Nominal 100 kHz, RC-type
Digital Hold-Off Filter 1 Hz to 50 MHz cut-off frequency
Software filter programs FPGA to hold-off
Maximum Voltage Without Damage
