| [1] | Analog capture for each channel is selectable between the BNC or POD inputs individually. |
| [2] | Dedicated A/D converter for each analog channel to support sample synchronous capture at all supported hardware rates on both analog channels or one analog and all logic channels. |
| [3] | Maximum bandwidth of analog channels captured using equivalent time sampling or used with the multi-band spectrum analyzer via 10:1 probes with prescale disabled and waveform amplitude captured to 10% full-scale. |
| [4] | User selectable analog input prescaler for use with low level signals or when 20MHz input bandwidth limiting is required. |
| [5] | Minimum measurable peak-to-peak sinusoidal waveform voltage when both resolution enhancement and input multiplier are enabled, when viewed as a waveform (Time) or viewed as a spectrum (Freq) and the minimum measurable average DC voltage (Mean). |
| [6] | Streaming capture sample rates for data logging and transient recorder applications. |
| [7] | Real-Time (Nyquist Limited) sample rates (captured per frame). |
| [8] | Equivalent-Time (not Nyquist limited) sample rates sample rates (captured per frame). Applies to periodic signals only. |
| [9] | Specifies the maximum effective number of bits (ENOB) achieveable with resolution enhancement enabled. |
| [10] | All specifications are quoted on the basis that the product is used with the apropriate BitScope software. |
| [11] | Supports 4 different generator types: VSR = Variable Sample Rate, DDS = Direct Digital Synthesis, CLK = Clock Generator, PRNG = Psuedo Random Number Generator. |
| [12] | Minimum and maximum frequency depends on generator type as indicated. |
| [13] | Uncalibrated frequency accuracy is specified (as defined by the BS120U reference crystal). May be calibrated to better than this if precision frequency reference is available. |
| [14] | Temperature Coefficient is that of the BS120U reference crystal. |
| [15] | Trigger, Burst and Clock modes may be configured to accept or generate a trigger or clock signal via the TimePort. |
| [16] | The maximum duration or delay depends on the sample rate. The maximum duration in all cases exceeds 1 hour but can extend far beyond this limit at lower sample rates. |
