OTHER CAPABILITIES
Markers – Single marker/delta marker; next
right, next left peaks; next lower, next
higher peaks; (highest) peak find; marker to
center frequency; select start/stop frequen-
cies; transpose
∆ markers.
Measurement Modes – Noise, carrier-to-
noise, bandwidth (user-definable "dB down"
points), 99% occupied bandwidth, signal
search, and cable TV measurements (see
Cable TV).
Time Delay Setup – Uses built-in
time-of-day clock to initiate measurement
sequences and sequence repeat interval;
START TIME, REPEAT INTERVAL, RUN N
TIMES.
PC-Based Software Package – Provides
report generation, test data analysis, data
history, channel tuning table definition,
user-defined program definition, limits
checking, alarming and 271X display
transfer.
Nonvolatile Memory –
Lithium battery backup, 124 K available;
used to save cable TV measurement results,
setup table parameters, large user-definable
key routines, antenna tables, and channel
tuning tables.
Saved Displays: 108 maximum.
Saved Front-Panel Setups: 36 maximum.
Digital Storage Display – Selectable acqui-
sition modes of positive peak only, positive/
negative peak; SAVE A, B, C, and active D
trace; up to four traces on screen; MAX
HOLD A, B; MIN HOLD C; B, C minus A;
TITLE MODE; digital storage off provides
analog display.
Ensemble Averaging – Provides weighted
averaging of display, results in reduction of
measured noise values and impulse signals.
Internal Preamp – Preamp can be switched
in/out of circuit (degrades flatness above
600 MHz, provides a maximum of 12 dB
sensitivity improvement).
Alternate Reference Level Units – dBm,
dBmV, dBV, dBµV, dBµW, dBµV/m (dBmV
and dBµV only in CATV measurement
mode).
dBµV/m Mode – Automatically compen-
sated field strength measurement with up to
five user-selected antennas.
User-Definable Power-On Status – Instru-
ment powers up to user-definable state or
supplied default settings.
Center Measure – Signal nearest center fre-
quency is centered with frequency and peak
amplitude automatically read out (not a
marker mode); the centered signal is
counted.
Signal Track – Drifting signal is kept at dis-
play center with correct frequency and peak
amplitude displayed.
Direct Plot/Print – Supports Epson FX and
LQ Series compatible Printers using RS-232
interface, or HPGL compatible plotters via
GPIB interface.
