U2701A/U2702A

Performance characteristics

[1]

(continued)

Vertical system: oscilloscope channels (continued)

Single-cursor accuracy ±{DC vertical gain accuracy + DC vertical offset accuracy + 0.2% full scale (~½ 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

Dual-cursor accuracy ±{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

Trigger System

Sources Ch 1, Ch 2, Ext (not applicable for TV trigger)

Modes Normal, single, auto trigger

Holdoff time 60 ns

Selections Edge, pulse width, TV

Edge Triggers on a rising or falling edge, alternating, or either edge of any source

Pulse width 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

TV 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.

Autoscale Single-button automatic setup of all channels

Oscilloscope channel triggering

Range (internal) ±4 div from center screen

Coupling AC (< 15 Hz)

LF reject (~ 35 kHz)

HF reject (~ 35 kHz)

External (EXT) triggering

Input impedance 1 MW: ≈ 16 pF

Maximum input CAT I 30 Vrms, 42 Vpk

Range DC coupling: trigger level ±1.25 V and ±2.5 V

EXT trigger pulse width > 2.5 ns
