to-Peak, Amplitude, Positive Overshoot, Negative Overshoot, High, Low.
DC balance 0.2 div at 1 mVdiv and up with the input 1 MW-DC coupled and 50 W terminated.
✓DC gain accuracy, Sample or
Average acquisition
This is the difference between the measured DC gain and the nominal DC gain,
divided by the nominal DC gain and expressed as a percent.
+/-3.0% step gain, derated at 0.1%/°C above 30°C.
DC voltage measurement
accuracy, average acquisition
mode
This is the accuracy of DC voltage DC voltage measurements acquired using
average of > 16 waveforms.
Average of > 16 waveforms: ±((DC gain accuracy) X |reading - (offset - position)| +
offset accuracy + 0.1 div + 1mV)
Analog bandwidth Defined in Section 4.6 of IEEE std 1057. The difference between the upper and lower
frequencies, at which the amplitude response, as seen in the data record, is 0.707
(-3 dB) of the response seen in the data record at the specified reference frequency.
Specifies only the -3 dB point. It does not include the in-band response.

Sample or Average
200 MHz models:
DC to >200 MHz for 1 mV/div through 10 V/div.
100 MHz models:
DC to >100 MHz for 1 mV/div through 10 V/div.
70 MHz models:
DC to >70 MHz for 1 mV/div through 10 V/div.
50 MHz models:
DC to >50 MHz for 1 mV/div through 10 V/div.
Analog bandwidth selections 20 MHz bandwidth limit ON/OFF
Upper-Frequency limit, 20 MHz
bandwidth limited, typical
This is the upper frequency for Analog Bandwidth when the instrument has 20 MHz
bandwidth limiting turned on.
20 MHz, ±25%
Bandwidth of all trigger paths are similarly limited, except the Aux-In, which is not
affected by BW Limit function. Each channel is separately limited, allowing different
bandwidths on different channels of the same instrument.
Lower- Frequency limit, AC
coupled
This is the lower frequency for Analog Bandwidth when the instrument is AC-
coupled.
≤ 10 Hz.
