Page 221 Mode Distance To Fault Distance To Fault Distance to Fault Description A signal is transmitted from the RF OUTPUT connector of the spectrum analyzer to the cable-under-test. The signals reflected from faults in the cable are received by analyzer. In performing this measurement, the analyzer uses frequency domain reflectometry. The changing interference of the transmitted and reflected signals contains information about the distance to one or more faults.

Page 231 Mode Distance To Fault In the following equations The Speed of Light (‘c’) in a vacuum is a constant value of 3e+8 m/s. Your test cable’s transmission speed (relative to light) is VRel. The Measured Distance (in meters) of the DTF measurement is determined by the following equation: Measured distance (in meters) = (1/4 * Number of points * c * VRel) / Freq.
Page 232 Mode Distance To Fault NOTE Although you can set your number of points to 256, 512, or 1024, you will only ever be able to save 256 data points when you save trace data. This is because only 256 points are ever used to display the trace, regardless of how many points you have used to actually make the measurement.
Page 233 Mode Distance To Fault distance to measured distance times the number of points you have specified. The higher the number of data points, the greater the measurement resolution. In most cases, the default resolution using 256 data points will be adequate to locate the faults, but if more resolution is needed you can increase the span between the start and stop frequencies (which will decrease the measured distance) or use the other approach, automatic frequency range.

Page 323 Using The Status Monitoring Subsystem When you are programming the instrument you may need to monitor instrument status to check for error conditions or monitor changes. You can determine the state of certain instrument events/conditions by programming the status register system. IEEE common commands (those beginning with *) access the higher-level summary registers.
Page 324 Using The Status Monitoring Subsystem What Are Status Registers What Are Status Registers The status system contains multiple registers that are arranged in a hierarchical order. The lower-level status registers propagate their data to the higher-level registers in the data structures by means of summary bits. The status byte register is at the top of the hierarchy and contains general status information for the instrument’s events and conditions.
Page 325 Using The Status Monitoring Subsystem What Are Status Register SCPI Commands What Are Status Register SCPI Commands Most monitoring of the instrument conditions is done at the highest level using the IEEE common commands indicated below. Complete command descriptions are available in the IEEE commands section at the beginning of the language reference.
Page 326 Using The Status Monitoring Subsystem How to Use the Status Registers How to Use the Status Registers A program often needs to be able to detect and manage error conditions or changes in instrument status. There are two methods you can use to programmatically access the information in status registers: •...
Page 327 Using The Status Monitoring Subsystem How to Use the Status Registers • Monitor a particular condition (bit). You can enable a particular bit(s), using the event enable register. The instrument will then monitor that particular condition(s). If the bit becomes true (0 to 1 transition) in the event register, it will stay set until the event register is cleared.
Page 328 Using The Status Monitoring Subsystem Using a Status Register Using a Status Register Each bit in a register is represented by a numerical value based on its location. See figure below. This number is sent with the command to enable a particular bit. If you want to enable more than one bit, you would send the sum of all the bits that you want to monitor.
Page 329 Using The Status Monitoring Subsystem Using a Status Register 5. You can do a similar thing with this register to only look at bit 9 using, STAT:QUES:ENAB 512. 6. The Status Questionable register output goes to the “Status Questionable Summary” bit 3 of the Status Byte Register.
Page 330 Using The Status Monitoring Subsystem Using the Service Request (SRQ) Method Using the Service Request (SRQ) Method Your language, bus and programming environment must be able to support SRQ interrupts. For example, BASIC used with VXI–11.3 (GPIB over LAN). When you monitor a condition with the SRQ method, you must: 1.
Page 331 Using The Status Monitoring Subsystem Using the Service Request (SRQ) Method measurement is in continuous mode, then restarting a measurement (INIT command) can cause the measuring bit to pulse low. This causes an SRQ when you have not actually reached the “end-of-measurement” condition. To avoid this: •...
Page 332 Using The Status Monitoring Subsystem Status Register System Status Register System The hardware status registers are combined to form the instrument status system. Specific status bits are assigned to monitor various aspects of the instrument operation and status. See the following diagram of the status system for information about the bit assignments and status register interconnections.

Page 334 Using The Status Monitoring Subsystem The Status Byte Register The Status Byte Register The RQS bit is read and reset by a serial poll. The same bit position (MSS) is read, non-destructively by the *STB? command. If you serial poll bit 6 it is read as RQS, but if you send *STB it reads bit 6 as MSS.
Page 335 Using The Status Monitoring Subsystem The Status Byte Register Description Description 0, 1 These bits are always set to 0. A 1 in this bit position indicates that the SCPI error queue is not empty which means that it contains at least one error message. A 1 in this bit position indicates that the data questionable summary bit has been set.
Page 336 Using The Status Monitoring Subsystem The Status Byte Register To query the status byte register, send the command *STB? The response will be the decimal sum of the bits which are set to 1. For example, if bit number 7 and bit number 3 are set to 1, the decimal sum of the 2 bits is 128 plus 8.

Page 338 Using The Status Monitoring Subsystem Standard Event Status Register The standard event status register contains the following bits: Description Description A 1 in this bit position indicates that all pending operations were completed following execution of the *OPC command. This bit is for GPIB handshaking to request control. Currently it is set to 0 because there are no implementations where the spectrum analyzer controls another instrument.
Page 339 Using The Status Monitoring Subsystem Standard Event Status Register plus 8. So the decimal value 136 is returned. In addition to the standard event status register, the standard event status group also contains a standard event status enable register. This register lets you choose which bits in the standard event status register will set the summary bit (bit 5 of the status byte register) to 1.
Page 340 Using The Status Monitoring Subsystem Operation and Questionable Status Registers Operation and Questionable Status Registers The operation and questionable status registers are registers that monitor the overall instrument condition. They are accessed with the STATus:OPERation and STATus:QUEStionable commands in the STATus command subsystem. See the figure at the beginning of this document.
Page 341 Using The Status Monitoring Subsystem Questionable Status Register Questionable Status Register The questionable status register monitors the instrument’s condition to see if anything questionable has happened to it. It is looking for anything that might cause an error or a bad measurement like a hardware problem, an out of calibration situation, or a unusual signal.
