TVTRIGGER
60 Hz / 525 lines : Source may be selected to be
any of the four inputs . Trigger level is adjustable
for
the selected source . Polarity is selected for
positive
or
negative synchronizing pulses . A trig-
ger occurs on the selected line and field of a 2/1
Interlaced composite video signal . Line numbering
is 1 to 263 for field 1 and
1
to 262 for field 2 . This
TV trigger mode is compatible
with
broadcast
standard M .
50 Hz /
625 lines : Same as 60 Hz / 525 lines, ex-
cept numbering is 1 to 313 for field 1 and 314 to
625 for field 2 . This TV trigger mode is compatible
with broadcast standards : B,C,D,G,H,I,K,K1,L and
N .
User-defined mode : Source may be selected to
be any one of the four Inputs . Trigger level is ad-
justable for the selected source . The trigger is
qualified with a high or low pulse that meets a
selectable time range . The trigger is an occur-
rence of a rising or falling edge of the source after
the qualifying pulse . The time settings for the
qualifier are selectable from 20 ns to 160 ms . The
trigger occurrence value is selectable from 1 to
16, 000, 000 .
NOTE : All TV trigger modes require a clamped
video
signal for
stable triggering . Use the HP
1133A TV/Video Sync Pod
to provide clamped
video output that can be used
with the HP
54501 A's TV triggering capabilities .
Holdoff : Holdoff is adjustable in 20 ns steps from
40 ns to 320 ms . A separate
holdoff setting is
available for each trigger mode except
DELAYED
TRIGGER, which is fixed to 40 ns .
Waveform Math
Two independent functions are provided for
waveformmath . The operators are +, -, X,
VS,
INVERT and ONLY . The vertical channels on any
of the waveform memories may be used as
operands for the waveform math . Sensitivity and
offset for these functions may be adjusted
independently .
Waveform Save
Four non-volatile memories and two volatile pixel
memories are provided . Waveform memories store
single-valued waveforms, such
as an averaged
waveform . If an envelope waveform
is stored to a
memory waveform, It will automatically
be stored
with the
upper
waveform in one
waveform memory
and the lower waveform in another . Pixel
memories store an entire screen of waveform data .
They are very useful for storing multiple, overlap-
ping waveforms and infinite persistence
waveforms .
DISPLAY
Data display resolution : 451 points horizontally by
256 points vertically .
Number of screens : 1,2, or 4 screens can - be selec-
ted . This allows the overlapping of channels or
memories for comparison, or viewing them on up to
4 data display areas .
Display Modes
Minimum persistence : One waveform data value
is displayed in each horizontal position of the dis-
play . The waveform is updated as the new data is
acquired for a particular horizontal position .

FIP 54501A GENERAL
INFORMATION
Table 1-2 . HP 54501A Operating Characteristics (continued)
Display Modes (continued)
Variable persistence : The time that each data
point is retained on the display may by varied from
200 ms to 10 seconds, or it may be displayed
infinitely .
Averaging : The
number of averages, (n) may be
specified in powers of 2, up to 2048 . On each ac-
quisition, 1 /n times the new data is added to
(n-1)/n of the previous value at each time coor-
dinate . Averaging operates
continuously, except
for the HP-IB
DIGITIZE command, for which
averaging ierminates
al a user-specified number of
averages .
Envelope : Provides a display of the running max-
imum and minimum voltage levels at each horizon-
tal position of a repetative waveform .
Graticules : The user may
select full grid, axes,
frame, or no graticule .
Connect-the-dots :
Provides a continuous display,
connecting the
sample points with straight lines .
Connect-the-dots
is operative for modes in which a
single valued
waveform can be connected, includ-
ing AVERAGE,
ENVELOPE, and MINIMUM
PERSISTENCE
modes .
Scroll mode : The HP 54501A automatically selects
scroll mode at time-per-division settings from 200
ms/div to 5 s/dlv if the scope is in AUTO mode, or
If the scope Is in TRIGGERED mode with the delay
at the left edge of the display set is greater than or
equal to 0 . Scroll mode
updates each data point
on the displayed
waveform as the data is acquired .
DELTAV /
DELTA t Markers : dual voltage markers
and dual time
markers are provided . Voltage
markers
may be independently assigned to chan-
nels,
memories, or functions .
AUTOMATIC PARAMETRIC MEASUREMENTS
Automatic Pulse
Parameter Measurements : The
HP 54501A performs 16
automatic pulse parameter
measurements from
the front panel and additional
measurements via
HP-IB including ALL,
OVERSHOOT, and PRESHOOT
. The standard
measurements are performed with 10%, 50%, and
90% voltage thresholds, as defined by IEEE
Standard 194-1977, "IEEE Standard Pulse Terms
and Definitions" .
User-definable Measurement
Thresholds : The HP
54501 A lets you set your own thresholds for auto-
matic measurements . Both the upper and the lower
thresholds may be set from 0% to 100% as long as
the upper
threshold value is
greater than or equal
to the
lower threshold . The mid threshold
is always
equal to the mid-value between the upper and
lower threshold .
Continuous measurements : may be turned,on or
off . With continuous measurements off, the voltage
and time markers are placed on the waveform to
indicate where the measurement is taken .
Measurement Statistics : The maximum, minimum,
average, and most recent of continuously updated
measurements are
calculated and
displayed . Any
three measurements may be selected .
Measurement Limit Test : Maximum and minimum
limits may be set for three of the automatic
measurements . These continuously updated
measurements are compared to the maximum and
minimum limits . If the measurements are found to
be outside the defined limits, the acquisition is
stopped and the waveform can be stored to a
memory or the screen can be sent to a printer . In
addition, an HP-IB Service Request can be
generated, so a
controller
can be
flagged
to
request
the waveform and the measurement infor-
mation via HPAB .
SETUP AIDS
Autoscale : Pressing the Autoscale button auto-
matically adjusts the vertical and horizontal deflec-
tion factors as well as the trigger level for a display
appropriate to the signals applied to the inputs .
The Autoscale feature requires a signal with a duty
cycle
greater than 0 .5% and a frequency greater
than
50
Hz .
