Digital Sampling Oscilloscope
TDS8000
Characteristics
Signal Acquisition
Acquisition Modes - Sample (normal), envelope, and average.
Number of Sampling Modules Accommodated - Up to four
dual-channel electrical and two single-channel optical sampling
modules.
Number of Simultaneously Acquired Inputs - 8 channels
maximum (8 electrical or 2 optical and 6 electrical).
Vertical Systems
Rise Time/Bandwidth - Determined by the sampling modules
used.
Vertical Resolution - 14 bits over the sampling module's
dynamic range.
Horizontal System
Main and Magnification View Timebases - 1 ps/div to
5 ms/div in 1-2-5 sequence or 1 ps increments.
Time Interval Accuracy -
Horizontal sensitivity < 21 ps: 1 ps + 1% of interval.
Horizontal sensitivity >21 ps:
8 ps + 0.1% of interval (short-term optimized mode).
8 ps + 0.01% of interval (locked to 10 MHz mode).
Horizontal deskew range : -500 ps to + 100 ns on any individual
channel in 1 ps increments.
Record Length - 20, 50, 100, 500, 1000, 2000 or 4000 samples.
Magnification Views - In addition to the main timebase, the
TDS8000 supports two magnification views. These
magnifications are independently acquired using separate
timebase settings.
Maximum Trigger Rate - 200 kHz.
Trigger System
Trigger Sources -
External direct trigger.
External pre-scaled trigger.
Internal clock trigger: internally connected to direct trigger.
Clock recovery triggers (from optical sampling modules):
internally connected to pre-scaled trigger.
Trigger Sensitivity -
External direct trigger input:
50 mV, DC - 4 GHz (typical).
100 mV, DC - 3 GHz (guaranteed).
Pre-scaled trigger input:
800 mV, 2-3 GHz (guaranteed).
600 mV, 3-10 GHz (guaranteed).
1000 mV, 10-12.5 GHz (typical).
Jitter -
Short-term Jitter Optimized Mode:
1.0 ps + 5 PPM of position (typical).
< 1.5 ps + 10 PPM of position (max.).
Locked to 10 MHz Reference:
1.6 ps + 0.05 PPM of position (typical).
<2.5 ps + 0.10 PPM of position (max.).
Internal Clock - Adjustable from 25 to 200 kHz (drives TDR,
internal clock output and calibrator).
Trigger Level Range - ±1.0 V.
Trigger Input Range - ±1.5 V.
Trigger Holdoff - Adjustable 5 µs to 100 ms in 2 ns increments.
Display Features
Touchscreen Display - 10.4 in. diagonal, color.
Colors - 16,777,216 (24 bits).
Video Resolution - 640 horizontal by 480 vertical displayed
pixels.
Math/Measurement System Measurements
The TDS8000 supports up to eight simultaneous measurements,
updated 3 times per second with optional display of per
measurement statistics (min, max, mean and standard
deviation).
Measurement Set -
Amplitude Measurements: High, Low, Amplitude, Max, Mid,
Min, Peak-to-Peak, + Overshoot, - Overshoot, Mean, Cycle
Mean, RMS, Cycle RMS, AC RMS, Gain.
Timing Measurements: Rise, Fall, Period, Frequency, + Cross,
- Cross, + Width, - Width, + Duty Cycle, - Duty Cycle, Burst
Width, Delay, Phase.
Area Measurements: Area, Cycle Area.
Eye Pattern/Optical Measurements: Extinction Ratio (Ratio, %,
dB), Eye Width, Eye Height, Crossing %, Duty Cycle
Distortion, Jitter (pk-pk, RMS), Noise (pk-pk, RMS), Q-Factor,
SNR, Average Optical Power.
Cursors - Dot, vertical bar and horizontal bar cursors.
Waveform Processing
Up to eight math waveforms can be defined and displayed using
the following math functions: Add, Subtract, Multiply, Divide,
Average, Differentiate, Exponentiate, Integrate, Natural Log,
Log, Magnitude, Min, Max, Square Root and Filter.
In addition, measurement values can be utilized as scalars in
math waveform definitions.
TDR System (TDS8000 with 80E04 Electrical Module)
TDR Channels - 2 per 80E04.
TDR Amplitude - 250 mV.
TDR System Rise Time - < 35 ps.
Time Coincidence Between TDR Steps - < 1 ps.
Source Resistance - 50 + 0.5 Ohm.
Typical Aberrations (at + 250 mV amplitude) -
