U2701A Datasheet, PDF (9/11 Pages) Agilent(Hewlett-Packard) – U2701A and U2702A USB Modular Oscilloscope

Performance Characteristics (continued)
Vertical system: oscilloscope channels (continued)
Single-cursor accuracy
Dual-cursor accuracy
±{DC vertical gain accuracy + DC vertical offset accuracy + 0.2% full scale (~1/2 LSB)}
Example: for 50 mV signal, scope set to 10 mV/div (80 mV full scale), 5 mV offset,
accuracy = ±{4.0% (80 mV) + 0.1(10 mV) + 2.0 mV + 0.5% (5 mV) + 0.2% (80 mV)}
= ±6.385 mV
±{DC vertical gain accuracy + 0.4% full scale (~1 LSB)}
Example: for 50 mV signal, scope set to 10 mV/div (80 mV full scale), 5 mV offset,
accuracy = ±{4.0% (80 mV) + 0.4% (80 mV)} = ±3.52 mV

Edge
Triggers on a rising or falling edge, alternating, or either edge of any source
Pulse width
TV
Triggers on a pulse width greater than, equal to, or less than a specified time limit, with
time limits ranging from 16 ns to 10 s.
Minimum lower limit: 8 ns
Minimum upper limit: 16 ns
Maximum pulse width setting: 10 s
Triggers on one of three standard television waveforms: NTSC, PAL, SECAM
TV trigger sensitivity: 0.6 division of sync signal. Modes supported include Field 1, Field
2, all fields, or any line within a field.
