Analog Bandwidth, DC Coupled
TDS 310:DC - ≥50 MHz
TDS 320:DC - ≥100 MHz
TDS 350:DC - ≥200 MHz; DC - ≥180 MHz for 2 mV/div
Cross Talk (Channel Isolation)
≥100:1 at 50 MHz with equal Volts/Div settings on each channel
Input Impedance, DC Coupled
1MW ±1% in parallel with 20 pF ±2.0 pF
Input Voltage, Maximum
±400 V (DC + peak AC); derate at 20 dB/decade above 100 kHz to
13 V peak AC at 3 MHz and above
Lower Frequency Limit, AC Coupled2
≤10 Hz
1Net Offset = Offset - (Position × Volts/Div). Net offset is the voltage level at the center of the AD converter dynamic range. Offset
Accuracy is the accuracy of this voltage level.
2The AC Coupled Lower Frequency Limits are reduced by a factor of 10 when 10X, passive probes are used.

Accuracy, Long Term Sample Rate
and Delay Time
±100 ppm over any ≥1 ms interval
Accuracy, Delta Time Measurements1,
2
For singleshot acquisitions using sample acquisition mode and a
bandwidth limit setting of FULL:
±(1 WI + 100 ppm |Reading| + 0.6 ns)
For repetitive acquisitions using average acquisition mode with
≥16 averages and a bandwidth limit setting of FULL:
±(1 WI + 100 ppm |Reading| + 0.4 ns)
1For input signals ≥5 divisions in amplitude and a slew rate of ≥2.0 divisions/ns at the delta time measurement points. Signal must
be acquired at a volts/division setting ≥5 mV/division.
2The WI (waveform interval) is the time between the samples in the waveform record. Also, see the footnotes for Sample Rate
Range and Equivalent Time or Interpolated Waveform Rates in Table 411 on page 412.
