NOTE: Passive high impedance probes are not suitable for high fidelity measurements above 100 MHz. The non- negligible (5-10 pF) tip capacitance loads the signal causing distortion and/or ringing when combined with the ground lead inductance. 3.3. Data Acquisition The table below summarizes the characteristics discussed in the sections that follow: Model Max. Sampling Rate Max. CONVER TERS PER CHANNEL/ CHANNELS Default Memory points/ channel Maximum Optional Memory/ channel Maximum Segments TTI

Pre- or post-trigger delays are just different aspects of the same trigger positioning parameter: • The condition of 100% pre-trigger indicates that all data points are acquired prior to the trigger, i.e. the trigger point is at the end of the acquired waveform. • The condition of 0% pre-trigger (which is identical to a post-trigger of 0) indicates that all data points are acquired immediately after the trigger, i.e. the trigger point is at the beginning of the acquired waveform. • The condition

The DP1400 can also use the PCI Bus at frequencies up to 66 MHz. All modules are compatible for either V I/O = 3.3 V or 5 V. 3.11.2. Environmental and Physical The modules have a Declaration of Conformity according to ISO/IEC Guide 22 and EN45014 and CE Marks of Compliance. The American Standard MIL-PRF-28800F has been used as the source for many of the characteristics specified below. Those indicated with a ‘*’ are compatible with Class 3 as defined in that standard. The front panels of the Com

4.2.3. Numeric Editor The numeric editor is shown in the control window at locations where numeric values are set. The Acqiris Numeric Editor enables easy input of numeric values, particularly those ranging over many decades. The numeric value can be changed in multiple ways. A number can be typed directly into the white number display area or alternatively, the Acqiris Numeric Editor may be used. In order to use the Acqiris Numeric Editor, click on the green numeric editor icon at the left of t

Only the parameters of the modules are stored in the configuration file. This means that parameters of the AcqirisLive program, such as channel activation and display mode choices are not included. 4.5. Store, Autostore and Conversion of Waveforms The store menu gives you two mechanisms to store waveforms. 1. The Store Waveform option allows you to store the last acquired waveform for the current channel. To store the last acquired waveform for each of the active channels, you must sequentially

4.9. Additional Waveform Information The Options menu also includes possibilities to obtain additional information about the waveform. In both cases described below the display will be updated after each acquisition. The “Show Segment Timestamps” option shows a display like the one below: It gives you the information needed to better understand the trigger times of the individual segments of an acquisition. By definition the first trigger of an acquisition occurs at t1=0.0. There are two columns

first sample control is ignored). When saving data to file, you will be prompted for a maximum number of segments per file. Banks for SMAR Some of the 10-bit Family modules are capable of acquiring data and being read out simultaneously. The -Bn option allows the internal memory of the digitizer to be divided into n banks. To observe the improved acquisition trigger rate achievable in this mode it is suggested to set up the desired conditions and then turn the event display off. The trigger out

CAUTION: Turn off the power of the PC; the PC may have to be unplugged to ensure that the PCI bus has no power available. CAUTION: Touch the antistatic package to a grounded object before removing the card from the package. Electrostatic discharge can damage the card. The standard cable pair provided each have a red connector on one end and a black connector on the other. Therefore the correct connection can be made by plugging the Red connector into the L0Rx socket and the Black connector into
