 | Pulse Profiling (PROF) A measurement mode where there is an incoming pulse and it is desired to acquire S-parameters at sub-intervals within that pulse. These values are mapped versus position (time) within the pulse. This can be visualized as a profiling pulse (the sub-interval segment/measurement width) that steps through the DUT output pulse in time increments and makes a measurement at each step. This measurement is often used to check the evolution of DUT behavior over the duration of the pulse due to thermal, trapping, or other effects. Point-in-Pulse (PIP) A measurement mode where an S-parameter is only to be acquired at one time point within a pulse (or more precisely, within a small time window/measurement width). This is usually somewhere in the middle of the pulse and is selected when transient effects associated with pulse edges are not a concern, but the DUT must operate in pulsed mode (for example, to minimize device heating). It is desired to see how the behavior at the point within the pulse changes over frequency or power ranges. Pulse-to-Pulse (P2P) A measurement mode similar to pulse profiling except the time interval is between multiple pulses rather than within a pulse. Longer time-scale transient effects (such as thermal or memory related effects) are of interest. This is usually a triggered measurement since the DUT often needs to be in a long-time-scale-equilibrium before the excitation starts. Continuous Point-in-Pulse (CPIP) A measurement mode similar to Point-in-Pulse which is adequate for many swept pulse measurements. However, there are cases, particularly related to DUT transient response, where more detailed control of the VNA sweep operation relative to the pulses and the measurements is required. This is the purpose of the Continuous Point-in-Pulse mode (CPIP) where the entire sweep of frequency or power is done during one acquisition. Continuous Profiling As in CPIP, Continuous Profiling (CProf) measurement also uses a single acquisition for an entire frequency or power sweep but is a generalization in data analysis relative to CPIP. In CProf, one is not restricted to a measurement window associated with each sweep point but one can have up to 25000 measurement windows dispersed over the entire sweep time or located in some subset of that range. The number of displayed points is equal to the number of profiling points. |

 | Marker The pulse Marker feature allows up to two markers to be set on the pulse display. The marker window can then zoomed in and back out. The feature is described further in Zoom Marker Resolution Opens a field to change the pulse acquisition rate. This allows the user to speed up the measurements by changing the acquisition rate. This is useful when measurements are made at lower rep rates which may not require a high resolution. As resolution changes, the maximum values of most other PulseView settings changes (maximum acquisition length increases proportionately with resolution; default is 2.5253 ns resolution and 0.5 s maximum acquisition length). Synch Toggles the pulse Synch source: • INTERNAL synchronizes the primary clock to the leading edge of an internally provided synch pulse. • CONTINUOUS provides continuous, unsynchronized full-speed data acquisition. • EXT. RISING/EXT FALLING synchronizes the primary clock to the leading edge of an externally provided synch pulse. The synch event can be triggered to either the rising or falling edge of the synch pulse (EXT. RISING or EXT. FALLING). When the Synch type selected is EXT. RISING or EXT. FALLING, an “Ext. Synch Marking” check box is made available on the PulseView Configuration | Measurement tab. This feature allows the use of the external Pulse Synch In signal to mark the data stream in lieu of using the internally generated T0 pulsed signal. When enabled, the internal pulse generators are disabled  PRI Pulse Repetition Interval – Sets the primary clock synch pulse period in units of time and is inversely proportional to the pulse repetition frequency (PRI = 1 / PRF). When a PRI value is entered, the PRF is computed automatically. PRI can also be set in the PULSEVIEW SETUP Menu. PRF Pulse Repetition Frequency – Sets the primary clock synch pulse repetition rate in units of hertz and is inversely proportional to the pulse repetition interval (PRF = 1 / PRI). When a PRF value is entered, the PRI is computed automatically. PRF can also be set in the PULSEVIEW SETUP Menu. Control Type Enabled only in CPIP or CProf modes. Choices are Sync and Time. Synch control requires that Trigger Out be connected to Pulse Synch In. This is noted with a tool tip that appears when a pointer is over the button, as well as on the PULSEVIEW SETUP menu. |

1. Set the measurement mode (the measurement mode is a per-channel setting that applies to all receivers). 2. Select the receiver and check if the measurement parameters are to be applied equally to all receivers. 3. Set the measurement parameters on a per-receiver or coupled basis. 4. When the Measurement tab is selected the Pulse generators on only during measurement toggle selection is only visible when measurement mode is Pulse Profile or Continuous Profile. Selecting this feature allows pulse generators to start up only when a measurement is taken. 5.
