HP 3314A Manual

Operation
Model 3314A
THE 3314A FRONT PANEL
(1) Status
This group contains the HP-IB status indicators and the LCL
key to switch control of the 3314A from remote to front panel
operation. When the LCL key is preceded by the BLUE shift
key, the 3314A displays its HP-IB address for 1/2 second. The
НР-ІВ address is set from the front panel and stored in non-
volatile memory. The factory setting is 7. See "How to
Change the 3314A's HP-IB Address" located in the HP-IB sec-
tion of this manual.
(2) Mode
The 3314A has 7 basic operating modes. The trigger signal,
either the 3314A’s internal trigger source or an external signal
you supply, is essential to every operating mode except FREE
RUN with sweep off.
FREE RUM Mode. Тһе 3314A outputs continuous Sine, Square,
Triangle or ARB functions. Continuous functions, sweeps and
ARB operations are allowed. See "How to Use the FREE RUN
Mode".
GATE Mode. The output is "gated" ON and OFF by the Trigger
‘level. Gated functions, sweeps and ARB operations are allow-
ed, See "How to Use the GATE Mode”.
N CYCLE Mode. The 3314A outputs a burst of N complete cycles
of the selected function, starting when a Trigger edge is
received. The N parameter sets the number of cycles from 1 to
1999. The start/stop phase is set with the Phase parameter
from -90? to +90°. See "How to Use the N CYCLE Mode".
1/2 CYCLE Mods. The 3314A outputs alternate 1/2 cycles of the
selected funtion when a Trigger edge is received. The start
phase of the first 1/2 cycle {and the stop phase of the second
1/2 cycle) is set with the Phase parameter from -90° to
+90°. See "How to Use the 1/2 CYCLE Mode".
Fin X Н Mode The 3314A will phase lock to the Trigger
(reference) signal and output a frequency "N" times the
reference frequency. The N parameter sets "N" from 1 to
1999. The frequency limits for both the 3314A and the
reference are from 5O0Hz to 20MHz. See "How to Use the
PHASE LOCK Modes".
Fin + N Mode The 3314A will phase lock to the Trigger
(reference) signal and output a frequency equal to the
reference frequency divided by "N". The N parameter sets
"М from 1 to 1999. The frequency limits for both the
3314A and the reference are Кот БОНх to 20MHz. See
"How to Use the PHASE LOCK Modes".
ARB Mode. The ARB mode redefines the 3314A as an Arbitrary
Waveform Generator. The output waveform consists of a
series of voltage ramps called vectors. The operator has con-
trol over the number of vectors, the length of each vector in
time and the height of each vector. Both continuous ARB func-
tions (FREE RUN Mode) and gated ARB (GATE Mode) are
allowed. See " How to Use the ARB Mode".
© Preset
The Preset key initializes the 3314A to its basic operating
state. This feature is especially useful to quickly recover from
complex operating states.
Store/Recall
Up to 5, non-ARB front panel control settings can be stored in
registers 1 through 5 to be recalled in the future. Register О is
reserved for the front panel setting at power off. іп addition, 6
ARB waveforms can be recalled from ARB registers O through
5. ARB waveforms are automatically stored as they are
created.
(5) External Trigger
One EXT Trigger is a signal you apply to the Trigger УО port
that satisifies the selectable slope and threshold conditions
(note that the Trigger 1/O port is an input when EXT Trigger is
selected). EXT Triggers are level sensitive for Gate; edge sen-
sitive for Burst, Phase Lock and Sweep operations.
Another EXT Trigger is the MAN key. You will have to press
this key twice when in Gate mode, to simulate a complete trig-
ger cycle (both levels), Once is sufficient for all other opera-
tions. The minimum signal that will consistently trigger the 3314A
is > 300тУр-р, centered on the selected trigger threshold
voltage.
There are two EXT Triggers available from the HP-IB, the
Group Execute Trigger (GET) and the " MN" programming com-
mand.
(6) Internal Trigger
The SW/TR IMTVL parameter sets the period of the internal trig-
ger {note that the Trigger I/O port is an output when INT trig-
ger is selected). This output signal is useful as a sync signal
during sweeps, gate and burst operations.

Function
The
MAIN
OUTPUT.
This
output
has
a
characteristic
output
im-
pedance
of
500.
Although
operation
into
other
than
БОО
is
` allowed, the actual AC amplitude and DC offset will be dif-
ferent from the displayed values and the quality of the func-
tions will be degraded at higher frequencies due to transmis-
sion line impedance mismatches.
The SYNC OUTPUT. This output has a characteristic output im-
pedance of 500 when terminated into < БОО. When terminated
into
2
500,
it
will
deliver
TTL
compatible
levels
of
O
to
>2.5V. The maximum unloaded voitage is limited to —3V.
The edges of the sync signal are coincident with the peaks of
the
sine
and
triangle
functions
and
coincident
with
the
edges
of the square function. This relationship is inverted by Function
Invert.
