■ Measurement Indices (optional input module types)
• Each module has two input channels.
• Besides logic modules (16 channels), Model 8847 comes standard with 16 logic inputs integrated in the
device.
Trigger functions
Trigger mode
MEMORY (high-speed recording) : Auto, Single, Repeat
RECORDER (real-time recording) : Single, Repeat
Trigger sources
CH1 to CH16 (analog), Standard Logic 16ch + Logic Unit (Max. 3 units
48 channels), External (a rise of 2.5V or terminal short circuit), Timer,
Manual (either ON or OFF for each source),
Logical AND/OR of sources
Trigger types
• Level: Triggering occurs when preset voltage level is crossed
(upwards or downwards).
• Voltage drop: Triggering occurs when voltage drops below
peak voltage setting (for 50/60 Hz AC power lines only).
• Window: Triggering occurs when window defined by upper
and lower limit is entered or exited.
• Period: Rising edge or falling edge cycle of preset voltage
value is monitored and triggering occurs when defined cycle
range is exceeded.
• Glitch: Triggering occurs when pulse width from rising or
falling edge of preset voltage value is underrun.
• Event setting: Event count is performed for each source, and
triggering occurs when a preset count is exceeded.
• Logic: 1, 0, ×, pattern setting,
Level setting resolution 0.1% of full scale (full scale = 20 divisions)
Trigger filter
OFF, setting range 0.1 to 10.0 divisions (MEMORY: high-speed
recording) ,
ON (10 ms fixed)/OFF (RECORDER: real-time recording)
Trigger output
Open collector (5 voltage output, active Low)
at Level setting: pulse width (Sampling period × data number
after trigger)
at Pulse setting: pulse width (2ms)
Other functions
Trigger priority (OFF/ON), pre-trigger function for capturing
data from before/after trigger event (memory), level display
during trigger standby, start and stop trigger for recorder (real-
time recording)
FFT function
(function available from version 2.00 onward)
Analysis mode
Storage waveform, linear spectrum, RMS spectrum, Power
spectrum, Cross power spectrum,
Auto-correlation function, Histogram, Transfer function, Cross-
correlation function, Impulse response, Coherence function,
Octave analysis
Analysis channels 1 or 2 selected channels out of all analog channels
Frequency range 133 mHz to 8 MHz, External, (resolution 1/400, 1/800, 1/2000,
1/4000)
No.of sampling points 1000, 2000, 5000, 10000 points
Window functions Rectangular, Hanning, Exponential
Averaging
function
Time axis / frequency axis simple averaging, Exponential
averaging, Peak hold (frequency axis),
Averaging times: 2 times to 4,096 times

■ Maximum Recording Time for the Memory Function
• Operation cannot be guaranteed when the time axis is longer than one year.
• Setting recording length to an arbitrary value allows increasing the 200,000 division limit up to a
maximum of 320,000 divisions in 1 division units.
