manual for grounding information.
Do Not Operate in Explosive Atmosphere
Do not operate this instrument in an area where flammable gases or fumes are present. Such operation could cause an
explosion.
Avoid Live Circuits
Electrical-shock hazards are present in this instrument. Theprotective instrument coversmust not be removed by operating
personnel. Component replacement and internal adjustments must be referred to qualifiedservicepersonnel.
Do Not Service or Adjust Alone
Do notservice or make internal adjustments to this instrument unless another person, capable of giving first aid and resusci-
tation, is present.

7D01 (SN 6020000 & up)
7D01 FEATURES
The 7D01 Logic Analyzer will store and display up to 16 channels of digital data when installed in a 7000-seriesmainframe.
-
The cursor function provides an intensified zone on the data display, and a corresponding numerical readout display shows
the logic state (1 or 0) for each displayed channel of data. The positlon of the cursor, relative to the trlgger, is also displayed
on the crt readout. Cursor readout is displayed in either 3-bitor 4-bit bytes.
-
Digital data can be stored in 3 formats:
4 channels at 1016 bitslchannel, 8 channels at 508 bitslchannel, or 16 channels at
254 bitslchannel. The sample rate is selectable from 10 nanoseconds to 5 milliseconds/sample (in
a 5-2-1sequence) when
-
using the internal time base, or can be used with an external clock signal (upto 50 megahertz).
The 7D01 can be
triggered from 4 sources: channel 0 data, an external signal, a bullt-in16-channelword recognlzer, or man-
ually. Phe triggered data can be produced following the trigger (POSTTRIG), centered around the trlgger (CENTER),or pre-
-
ceedlng the trigger (PRE TRIG). The input threshold can be varied from minus 12 volts to plus 12 volts, or set to plus 1.4
volts for
TI-L logic levels.
-
The Word Recognizer produces an output when the logic states of the 16 input data channels match the states of the corres-
ponding Word Recognizer switches. "Two qualifier inputs are also provided to enable the Word Recognizer output. The Word
Recognizer operates in either the synchronous or asynchronous mode. A variable filter (toat least 300 nanoseconds)allows
.-
rejection of brief false-triggersignals.

OPERATING INSTRUCTIONS
This section includes a description of the 7D01 front-panelcontrols, connectors, and indicators. Also included is detailed
operating information, some basic application proceduresand
a functional check procedure. Refer to Section 1, General
Information, for aglossary ofterms and installation instructions.
FRONT-PANEL CONTROLS,
CONNECTORS, AND INDICATORS
Refer to Detailed Operating Information for a discussion of
the auxiliary functions available with the internal selectors,
^]-helocation and function of the front-panel controls, and the input and output signals available through the Data
connectors, and indicators are illustrated in Figure 2-1. Out connector.
DETAILED OPERATING INFOWMAVON
AUXlLlARY FUNC'TIONS
Several auxiliary functions can be selected by connectors
and jumpers located inside the 7D01. A 25-pin Data Out
connector is also located inside the 7D01 to provide various
input and output signals for use with external equipment.
The following information describes the auxiliary functions
with procedures for making the appropriate internal
connections.
Display Clock Source Selector (P835)
Two-pinjumper which determines whettler the 7D01 is to
be used for display only, or for display and data output
(serialand parallel data at the Data Out connector).
When the 7D01 is used for data displays, P835 must be set
to Internal Display Clock (see Fig. 2-2).When the 7D01
is
to be used for display and data output (serialand parallel),
P835 must be
set to External Display Clock (see Fig. 2-2)
and an external display clock signal must be applied to pin
3 of Data Out connector J120 to synchronize the data out-
put. "The rate per bit of the serial and parallel output data
is
determined by the rate of the external display clock signal
applied to pin 3 of Data Out connector J120. If adisplay is
desired, as well as serial and parallel data, the external dis-
play clock signal repetition rate must be approximately
2 microseconds. The internal display clock signal
is not
available as an output.
Full DisplayIFirst Trigger Selector (P617)
Two-pin jumper which determines whether data is displayed
at the first acceptable trigger after the memory has addres-
sed one full block of data, or whether data
is displayed
after the first acceptable trigger.
REV. A, MAR 1977
-
When P617 IS set to Full Display (see Fig. 2-2),the memory
stores one complete block of data and then accepts the
next trigger. The Full Display position is recommendedfor
most repetitive signal applications. Ifatrigger is expected
soon after a reset pulse, or if the wait betweendisplaysat
slow sample rates is objectionable, P617 can be
set to the
First Trigger position (see Fig. 2-2). Refer to Synchronous
and Asyr~chronousData Sampling for more information.
Signal Selector (P300)
Internal multi-pinconnector P300 provides 5 signals for
connection to 3 outputs on Data Out connector J120. Any
3 of the
5 signals can be used for external use. Figure 2-3
shows the locationof P300, and identifies the pin assign-
ments as they are connectedwhen shipped from thefactory.
To change signal outputs at J120, movethe jumper connec-
tions at P300 (referto Fig's. 2-3and 2-4).
FORMAT OUTPUT. Two outputs (P300 pins 1 and 2)
provide ECL-level outputs which indicate the channel
selected by the front-panel DATA CHANNELS switch.
Table 2-1shows the ECL levels at pins
1 and 2 of P300for
each position of the DATACHANNELS switch.
