Product Information
BS325U is a high performance USB connected Mixed Signal Scope and Data Acquisition System.
BS325U offers all the benefits of its popular predecessor (BS310U) but supports eight times more data per frame, built-in record/replay waveform generator, dedicated external trigger and probe calibration, isolation from the PC and simultaneous capture on all 10 channels (full details).
A plug and play USB peripheral interface compatible with USB 2.0 and USB 1.1 ports is built-in.
If you prefer network connectivity please see the functionally equivalent BS325N model.

| [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 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] | Supports 2 different generator types: AWG = Arbitrary Waveform Generator, LPG = Logic Pattern Generator. |
| [11] | Minimum and maximum frequency depends on generator type as indicated. |
| [12] | Uncalibrated frequency accuracy is specified (as defined by the BS325 reference crystal). May be calibrated to better than this if precision frequency reference is available. |
| [13] | Temperature Coefficient is that of the BS325 reference crystal. |
