Item Specifications
Addition, subtraction, multiplication, and division between channels with coefficients
Expression: +, –, ×, and ÷
Computation format: A, B, C can be defined
Addition: (A*S1)+(B*S2)+C
Subtraction: (A*S1)–(B*S2)+C
Multiplication: (A*S1)×(B*S2)+C
Division: (A*S1)÷ (B*S2)+C
Selectable range of coefficients A, B, and C: ±9.9999E+30 to ±9.9999E–30
Knocking filter Filter that sets the output to 0 when the source channel signal is less than or equal the elimination
level.
Selectable filter FIR: HPF/BPF
IIR: HPR/BPF
Differentiation: LPF (bandwidth limit) ON/OFF possible
Variable ON/OFF When variable is set to OFF (zooming in or out by setting the zoom rate)
Value/Div: 123 Value/Div settings can be specified using the V/DIV knob (1-2-5 steps).
10.00E–21 [Value/Div] to 500.0E+18 [Value/Div]
When variable is set to ON (vertical zoom/expand according to the upper and lower limits of the
display range)
Upper and lower limits: ±5.0000E+22 [Value/Div]/±1.0000E–23 [Value/Div]
Display range: Up to ±5.0000E+21.(500.0E+18 [Value/Div]×10 [Div])
The display will be clipped at higher values.
Computation delay: [4 samples + the computation delay of the digital filter] (For details, see
appendix 6.)
The computation time of filters is proportional to the sample rate of the
DSP channel.
If the output result is specified as a source of another DSP channel, the
computation delay increases.
Can specify analog channels (CH1 to CH16) as computation sources. The computed result of a
DSP channel can also be specified as a computation source of another DSP channel. However,
only DSP channels with a channel number smaller than itself can be specified.
The maximum sample rate of analog channels is 5 MS/s when a DSP channel is turned ON.
Recorder Mode (DL750P only)
Item Specifications
Realtime recording on T-Y waveform recording/numeric value recording: Output to the chart in realtime.
the built-in printer X-Y waveform recording: Starts data acquisition with START and
generates X-Y waveforms in realtime. Outputs
X-Y waveforms to the chart with STOP.
Length of data saved to T-Y waveform recording: Fixed to 2.5 MW Automatically saves up to 1000 divisions of data
memory while realtime (depending on the chart speed).
recording X-Y waveform recording: Fixed to 1 MW
Recording start trigger Recording can be started using a trigger by setting the trigger mode.
Auto: Trigger disabled. Continuous recording. Recording starts with measurement start.
Log: Trigger disabled. Recording stops when the memory storage length of data is acquired.
When short recording is specified, recording stops when shot recording ends.
Single: Trigger enabled. Recording starts after a trigger detection.
When short recording is specified, recording stops when shot recording ends.
Repeat: Trigger enabled. Recording starts after a trigger detection.
Selectable only when shot recording is specified. Reenters trigger-wait state after short
recording.
Chart speed 20 mm/s, 10 mm/s, 5 mm/s, 2 mm/s, 1 mm/s, 100 mm/min, 50 mm/min, 25 mm/min, 20 mm/min,
