Page 13: Receiver
Introduction Receiver The receiver uses the Standard Tracking Mode to collect Frequency data. The Standard Tracking Mode is capable of collecting information at either of the following resolutions: • Low resolution data monitoring (8 bit ADC) • High resolution data monitoring (12 bit ADC) Standard Tracking Mode The receiver’s Standard Tracking mode, collects voltage and current information for user specified fundamental frequencies. Up to three fundamental frequencies can be specified to monitor. For each fundamental frequency, up to 10 harmonic frequencies can also be monitored (in addition to the fundamental) and a subset of up to 6 mixing products can also be monitored. The receiver reports voltage amplitude, current amplitude, and phase information as a data set for each specified fundamental frequency. Example ‐ Select 2 MHz as the first fundamental frequency (F1) and 13.56 MHz as the second fundamental frequency (F2). Specify two harmonics for F1 (H1 and H2) and one harmonic for F2 (H1), the results would be grouped as a set for each fundamental frequency as shown in the following table (note that H0 is the same as the fundamental frequency and that N represents the Nth data set). Dataset Fundamental Harmonic Data F1(2MHz) H0(F1) 2.0MHz,V,I,phase F1(2MHz) H1(2F1) 4.0MHz,V,I,phase F1(2MHz) H2(3F1) 6.0MHz,V,I,phase F2(13.56MHz) H0(F2) 13.56MHz,V,I,phase F2(13.56MHz) H2(3F2) 40.68MHz,V,I,phase … … …... -
Page 14: Theory Of Operation
BDS Cal Cart Theory of Operation The BDS Cal Cart is a real‐time RF measurement system that consists of a sensor, receiver and a load. The sensor simultaneously measures voltage and current (both magnitude and phase of each) and sends the data to the receiver. The BDS Cal Cart is calibrated as a system and the components are not interchangeable. The receiver processes the sensor data and passes the data to the laptop. The receiver consists of RF input conditioning circuits, A/D converters, a high‐speed signal processor, and input / output connectors. See Figure 2. The A/D converters convert the analog RF signal to digital information for processing; the high‐speed signal processor converts the signal from the time domain to the frequency domain while maintaining the correct phase relationship of each harmonic to its fundamental frequency. The output of the receiver contains information about the RF including up to three fundamental frequencies (amplitude of both voltage and current and their phase for each fundamental frequency) and up to 10 overtones for each fundamental frequency (amplitude of both voltage and current and their phase for each harmonic, and also the phase relationship of each harmonic to the voltage component of its specific fundamental frequency). With this data set (voltage, current, and phase), power ( ) and impedance ( ) can be determined for each fundamental and harmonic frequency. Users can choose number of fundamental frequencies (up to three) and associated harmonics (up to 10 for each fundamental frequency) that are acquired and processed. Choosing a small number of fundamental and harmonic frequencies reduces the computing time and, therefore, provides output data faster than choosing a larger number of fundamental and harmonic frequencies. See "Specifications" on page 37. Figure 2 Receiver Block Diagram... -

Page 18: Chapter 4 Bds Graphical User Interface Description
Chapter 4 BDS Graphical User Interface Description Overview The BDS GUI is used to configure the receiver and obtain measurement data from the system. There are two sampling resolutions for Standard Tracking operating mode: 8‐bit, 1G sample/second, and 12‐bit, 200M sample/second. The 8‐bit sampling mode has a tracking range of 301 kHz ‐ 100 MHz at the expense of narrower dynamic range and less repeatability as compared to 12‐bit mode. The 12‐bit sampling mode also has a tracking range of 301 kHz ‐ 100 MHz with a wider dynamic range, higher accuracy, and better repeatability than the 8‐bit mode. The receiver accurately measures voltage (V), current (I) and phase () in Standard Tracking operating mode. The BDS GUI uses these three basic parameters to derive other quantities such as power and impedance. Menu Bar File Menu Provides standard file operations for opening and saving Documents.

Page 29: Scan Mode Options
BDS Graphical User Interface Operation Scan Mode Options Frequency Selection The Frequency Selection page is used to define a set of frequencies for the BDS Cal Cart receiver to monitor while in Frequency Tracking Mode. Note: All options including harmonic and intermod selection, tolerance, filter width, and tracking quality, apply to a fundamental frequency. Figure 11 Frequency Selection Dialog Resolution — This field is always set to use “Auto”. Auto mode will automatically decide which converter to use based on the selected frequency list. The 12‐bit converter is used if all frequencies in the list are less than 100 MHz. A switching algorithm is used for a list that contains frequencies ranging from 307 kHz ‐ 100 MHz. Fundamental — Enter a custom generator frequency or select from the list of generator frequencies commonly used in the semiconductor industry. Note: Select all other options for the fundamental before adding it to the list of selected frequencies. Options include harmonic selection, intermod selection, and tolerance settings. F2 Frequency — Select another fundamental from the list to use as the “F2” frequency in an intermodulation product. Note: The F2 frequency must have already been added to the selected frequencies list. Note: An intermod is combination of two frequencies in the form: IMD = F1+nF2, where n is one of {‐ 3,‐2,‐1,1,2,3}. - Page 30 BDS Cal Cart Intermod — Select the number of intermodulation products reported for the fundamental. Up to 6 IMD products can be selected for a fundamental (3 pairs): F1 +1/‐1 F2 (2 IMD products). F1 +2/‐2 F2 (4 IMD products). F1 +3/‐3 F2 (6 IMD products). Tolerance — The Tolerance field defines the tracking filter window as a percentage from the center of the fundamental frequency. This gives the frequency range of a generator for a frequency. Example ‐ For a 2 MHz generator that moves from 1.8 to 2.2 MHz, you would enter a tolerance of at least 10%. The input value range for this field is 0.01 to 20.47%. The maximum tolerance for a frequency is lim‐ ited based on the following formula: 5/frequency in MHz * 100. Filter Width & Track Quality — These are advanced parameters used to fine‐tune the frequency tracking algorithm. Note: It is recommended that these settings are kept at their default values of 0.1 and 0.01%, respec‐ tively. Filter Width is used to widen or narrow the filters used to determine frequency lock. Default for Filter Width: 0.1%. Note: Filter Width ranges from 0.01 to 2.047%. Track Quality is used to adjust lock speed at the expense of accuracy. The higher the value, the lower the quality and the lower the frequency accuracy. Default for Track Quality: 0.01%. Note: Track Quality ranges in value from 0.0001 to 0.1023%. Selected Frequencies — Displays all frequencies that have been added to the measurement configuration. Frequencies are listed in MHz. Column headers (from left to right): ...

Page 32: Averaging
BDS Cal Cart Averaging The BDS Cal Cart Receiver offers two types of data averaging for Standard Tracking Mode: Fixed (Simple) or Moving. Both averaging modes will reduce signal‐to‐noise ratio in a measurement. Averaging is performed in the receiver. Figure 14 Averaging Dialog A simple average will take a number of measurements and then compute and report the average value after the number of measurements has been sampled. This averaging mode will increase the data update rate by the number of averages requested. Example ‐ If the data update rate for 1 measurement dataset is 10ms, then it will take about 40ms to average 4 measurements and produce the result. A user can average up to 16 measurements using Simple averaging. The Moving average mode averages data over time using a sliding filter window. The average window size is specified as a power of 2 ranging from 2 to 128 measurements. The difference between Moving and Simple averaging is that the moving average doesn’t wait for the buffer to fill before computing a result, it simply adds a new measurement to the buffer and computes and reports the result. It removes the oldest measurement if the buffer is full before adding the new measurement. This provides little impact the data update rate, depending on the measurement set. V/I Noise Threshold parameter (Moving Average Mode) is used to determine when to clear the filter buffer – when the signal (voltage or current) exceeds this threshold the buffer is cleared to provide a fast response to the measurement system. -
Page 33: De-Embedding
BDS Graphical User Interface Operation De-embedding De‐embedding is used to mathematically rotate the measurement plane from the center of the BDS Cal Cart Sensor probe toward either the load or the signal source. In doing so, it adjust measurements made by the probe in order to get a reading at a different segment of a line section. Figure 15 De-embedding Dialog The de‐embedding algorithm accounts for losses in the RF delivery system. The de‐embedding options allow users flexibility to enter segment parameters in different formats to match segment spec or data sheets. Line section impedance is entered as either inductance and capacitance or Z0 in Ohms. Dielectric is entered as either propagation velocity as a fraction of the speed of speed of light or in Er. Loss can be entered as Ohms, dB, or Nepers. Misc Enable relative phase measurements (required for waveform reconstruction) This option is used to enable relative phase calculations. Relative phase is the phase of a harmonic relative to its fundamental tone. It is required for waveform reconstruction. Figure 16 Misc Dialog Note: Relative phase calculations add significant processing time and will slow down the data update. Note: Pulsed RF Mode options are not available for the BDS Cal Cart system. -
Page 34: Free Run
BDS Cal Cart Free Run Figure 17 Free Run Dialog Use the Free Run scan mode to scan for data until the specified number of datasets have been collected or a timer expires, whichever happens first. If the “Continuous Scan” check box is checked, then data is scanned continuously and the timer is ignored. In Continuous Scan, when the indicated number of datasets has been collected, the oldest data will be discarded to make room for new data. Example ‐ If the “No. Dataset” field is set to 2000 and “Continuous Scan” is checked; the BDS GUI will continuously scan for fresh data. After 2000 datasets are captured; the oldest datasets are discarded to make room for new datasets. Trigger Figure 18 Trigger Dialog Use the Trigger scan mode to wait for an event to occur before collecting data. Select the threshold unit(s) and levels. A trigger event will occur when any of the selected Voltage, Current, or Delivered Power thresholds are detected. Pre‐ and post‐event windows can be specified to include data that is captured before and after the trigger event. The Trigger Capture Limits are included to limit the number of datasets acquired, similar to the Free Run limits. -
