Standard Accessories - Tektronix 2247A Operator's Manual

Introduction
The vertical deflection system has four Input channels. Two channels have
11 basic deflection factors from 2 mV to 5 V per division, and two channels
have two basic deflection factors of O. 1 V and O. 5 V per division. Basic
deflection factors can be extended with attenuator probes. VOL TS/DIV
readouts are switched to display the correct vertical scale factors when
properly coded probes are connected to the vertical input connectors.
The horizontal deflection system provides single, dual, or delayed sweeps
from 0.5 s to 20 ns per division (delayed sweep, 5 ms to 20 ns per division) .
The trigger system provides stable triggering over the full bandwidth of the
vertical deflection system.
Alphanumeric crt readouts of the vertical and horizontal scale factors are
displayed at the bottom of the screen. On-screen vertical and horizontal
cursors provide accurate voltage, time, frequency, and phase measure-
ments; measurement values are displayed at the top of the crt.
Measurement features Include voltage, time , frequency, and phase ,
counter/timer measurements, and risetime/falltime or propagation delay .
Voltage measurements Include positive peak, negative peak, peak- to -
peak, and average de levels, measured over the entire display or a selected
portion ( gated measurements) .
Counter /timer measurements Include frequency, period, width, totalize ,
frequency ratio, gated frequency, gated period, gated width, gated events ,
delta time, one-over-delta time, phase, rise/fall time, and propagation
delay, using an Internal or external frequency standard. Counter /timer
measurements can be averaged to increase the number of displayed digits ,
and measurement trigger points can be Indicated with cllrsors on screen.
Positionable cursors allow absolute voltage, voltage difference, time dif-
ference, frequency, and phase measurements. SmartCursors® visually
track voltage measurements, trigger levels and ground and may be
selectively displayed with the waveforms. Time, frequency, and phase
measurements referenced to the trigger event or between two user-
selected events are available In ALT and B horizontal modes.
By pressing a single button (AUTO SETUP), the front-panel controls can
be set up to produce a usable waveform display based on the voltage and
time characteristics of the Input signals.
The Store/Recall system lets you store and recall up to 20 different front -
panel setups. Stored setups can be arranged In sequences as required for
specific applications.
