The Option 14 Panel (Option 14
instruments only) allows access to
three communications interfaces: a
Centronics parallel port, an RSĆ232
interface, and a GPIB interface. It also
includes a VGA video compatible
output port and a power connector for
the Option 3P printer.
The power connector accepts line
voltage to power the instrument.
See page 1Ć3 for a list of power cord
and connector options.
The fuse drawer holds the line fuse.
See page 8Ć9 for fuse replacement
procedures.
You can use the Centronics, RSĆ232,
and GPIB interfaces to transmit
hardcopy data; see page 3Ć43 for
hardcopy procedures.
You can use the GPIB and RSĆ232
interfaces to operate and program the
oscilloscope from a GPIB controller;
see the TDS 310, 320, & 350
Programmer Manual for more

1The trigger position errors are typically less than the values given here. These values are for triggering signals having a slew
rate at the trigger point of ±0.5 division/ns.
2The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the characterisĆ
tics Sample Rate Range and Equivalent Time or Interpolated Waveform Rates in Table 4Ć11 on page 4Ć12.
3The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on the
selected slope. The trigger point must not switch between opposite slopes on the waveform, and the display must not roll"
across the screen on successive acquisitions. The TRIG'D LED stays constantly lighted when the SEC/DIV setting is 2 ms or
faster but may flash when the SEC/DIV setting is 10 ms or slower.

1Displayed vertically with 25 digitization levels (DLs) per division and 10.24 divisions dynamic range with zoom off. A DL is the
smallest voltage level change that the 8Ćbit AĆD Converter can resolve, with the input scaled to the volts/division setting of the
channel used. Expressed as a voltage, a DL is equal to 1/25 of a division times the volts/division setting.
2The sensitivity ranges from 2 mV/div to 10 V/div in a 1-2-5 sequence of coarse settings. Between consecutive coarse settings, the
sensitivity can be finely adjusted with a resolution of 1% of the more sensitive setting. For example, between 50 mV/div and 100ĂmV/
div, the volts/division can be set with 0.5 mV resolution.

1The range of realĆtime rates, expressed in samples/second, at which a digitizer samples signals at its inputs and stores the samples
in memory to produce a record of timeĆsequential samples
2The Waveform Rate (WR) is the equivalent sample rate of a waveform record. For a waveform record acquired by realĆtime sampling
of a single acquisition, the waveform rate is the same as the realĆtime sample rate; for a waveform created by interpolation of realĆ
time samples from a single acquisition or by equivalentĆtime sampling of multiple acquisitions, the waveform rate is faster than the
real time sample rate. For all three cases, the waveform rate is 1/(Waveform Interval) for the waveform record, where the waveform
interval (WI) is the time between the samples in the waveform record.

Check DC Voltage Measurement Accuracy
Performance of this procedure requires input voltages up to 98 VDC.
Contact with live circuits could cause injury or death. Be sure to set
the DC calibration generator to 0 volts before connecting, disconĆ
necting, and/or moving the test hookup during the performance of
this procedure.

Avoid the use of chemical cleaning agents that might damage the
plastics used in this oscilloscope. Use only deionized water when
cleaning the menu buttons or frontĆpanel buttons. Use a 75% isoproĆ
pyl alcohol solution as a cleaner and rinse with deionized water. BeĆ
fore using any other type of cleaner, consult your Tektronix Service
Center or representative.
Avoid the use of high pressure compressed air when cleaning dust
from the interior of this instrument. (High pressure air can cause
ESD.) Instead, use low pressure compressed air (about 9 psi).

WARNING
To avoid injury: Use care when handling a monitor. If you break its
display tube it may implode, scattering glass fragments with high
velocity and possibly injuring you. Wear protective clothing,
including safety glasses (preferably a fullĆface shield). Avoid striking
the display tube with or against any object.
To avoid damaging the monitor: Store the monitor with its display
tube face down in a protected location, placing it on a soft,
nonabrasive surface to prevent scratching the face plate.
