Time and cross-hair cursors indicate Hz and dB or volt val-
ues when an FFT spectrum analysis is made.
Menus:
Standard: Waveform storage; acquisition parameters;
memory status; store/recall front-panel configurations,
RS-232-C configuration; plotter setup.
Optional: (WP01/WP02) averaging, arithmetic, functions,
extrema, smoothing, FFT and frequency domain averag-
ing.
REMOTE CONTROL
All the front-panel controls, including variable gain, offset
and position controls (not cursor positioning), and all the in-
ternal functions are programmable.
RS-232-C ports: Two: for computer/terminal control and
plotter connection. Asynchronous up to 19200 baud.
GPIB port: (IEEE-488). Configured as talker/listener
for
computer control and fast data transfer; 400 kilobytes/sec
maximum. ASCII or binary. The address switches are on the
rear panel.
It includes LeCroy MS02 (MASP) IBM-PC-based software
for mass storage and remote control applications. For further
details on MASP software, please refer to the MS01/02 data
sheet.
PROBES

Standard probes: Two model P9010, xl0 attenuating pas-
sive probes with 10 M~ input impedance in parallel with a
5.5 pF capacitance.
Probe power: Two power outlets on the rear panel provide
_+ 15 V and + 5 V DC for active probes.
GENERAL
Temperature: 5 to 40°C rated; to 50°C operating.

EMI Immunity: The 9400A complies with the following stan-
dards: IEC 801, VDE 0871, FCC PART 15 and SEV.
Safety standards: The 9400A complies with the following:
IEC-348, ASE 3453 and VDE 0411.
Power required: 110 or 220 V AC, 48 to 65 Hz, 200 W.
Battery backup: NiCd batteries maintain front-panel set-
tings for 6 months minimum.
Dimensions: (HWD) 19.2 x 36.5 × 46.5 cm,
(7 1/2 x 14 3/8 x 18 3/8 inches).

OPTIONS FOR THE 9400A
9400AOP01
: _+ 1% DC high-precision option. A certificate
of
traceability is provided with this option.
9400AOP03: Printer drive for HP 2225 Think Jet.
WAVEFORMPROCESSING 9400AWP01, AND
9400AWP02
Routines are called and set up via menus. Extensive signal
processing in both time and frequency domains is provided
by optional firmware packages. These include FFT spectrum
analysis, arithmetic functions, integration, differentiation,
square root, square, averaging (continuous and summation)
and smoothing, as well as Extrema monitoring.
For additional information refer to data sheets WP01 and
WP02.

RECORD LENGTH (no. of points)
With option WPO 1 installed, the 9400A becomes a fast signal a verager
(both summation and continuous). A s many as 100, 000 points/sec are
averaged with record lengths chosen by the user up to a maximum of
32,000. The graph above displays the relationship between record
length and the number of signals/sec averaged.
