Page 69: Bw/Avg
Instrument Functions: A - L BW/Avg 2.3 BW/Avg Activates the resolution bandwidth function, and displays the menu keys that control both the bandwidth and averaging functions. 2.3.1 Res BW Enables you to select the 3.01 dB resolution bandwidth (RBW) of the analyzer in 10% steps from 1 Hz to 3 MHz, plus bandwidths of 4, 5, 6, or 8 MHz.
Page 70 Instrument Functions: A - L BW/Avg For applications that require 6 dB resolution bandwidths, it is possible to use NOTE an equivalent 3 dB resolution bandwidth.

Page 350 Using the STATus System Using the Status Registers To monitor a condition: 1. Determine which register contains the bit that reports the condition. 2. Send the unique SCPI query that reads that register. 3. Examine the bit to see if the condition has changed. You can monitor conditions in different ways.
Page 351: Using A Status Register
Using the STATus System Using the Status Registers Using a Status Register Each bit in a register is represented by a numerical value based on its location. See Figure 6-1 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 are interested in.
Page 352 Using the STATus System Using the Status Registers Generating a Service Request To use the SRQ method, you must understand how service requests are generated. Bit 6 of the status byte register is the request service (RQS) bit. The *SRE command is used to configure the RQS bit to report changes in instrument status.

Using the STATus System Using the Status Registers Status Byte Register The RQS bit is read and reset by a serial poll. MSS (the same bit position) 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. For more information refer to IEEE 488.2 standards, section 11.

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 357 Using the STATus System Using the Status Registers 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 378: Questionable Integrity Register
Using the STATus System STATus Subsystem Questionable Frequency Negative Transition :STATus:QUEStionable:FREQuency:NTRansition <number> :STATus:QUEStionable:FREQuency:NTRansition? This command determines which bits in the Questionable Frequency Condition register will set the corresponding bit in the Questionable Frequency Event register when the condition register bit has a negative transition (1 to 0).
Page 379 Using the STATus System STATus Subsystem Questionable Integrity Enable :STATus:QUEStionable:INTegrity:ENABle <number> :STATus:QUEStionable:INTegrity:ENABle? This command determines which bits in the Questionable Integrity Condition Register will set bits in the Questionable Integrity Event register, which also sets the Integrity Summary bit (bit 9) in the Questionable Register.
Page 380: Questionable Integrity Signal Register
Using the STATus System STATus Subsystem Questionable Integrity Positive Transition :STATus:QUEStionable:INTegrity:PTRansition <number> :STATus:QUEStionable:INTegrity:PTRansition? This command determines which bits in the Questionable Integrity Condition register will set the corresponding bit in the Questionable Integrity Event register when the condition register bit has a positive transition (0 to 1).
Page 381 Using the STATus System STATus Subsystem Questionable Integrity Signal Event Query :STATus:QUEStionable:INTegrity:SIGNal[:EVENt]? This query returns the decimal value of the sum of the bits in the Questionable Integrity Signal Event register. The register requires that the associated PTR or NTR filters be set NOTE before a condition register bit can set a bit in the event register.
Page 382: Questionable Integrity Uncalibrated Register
Using the STATus System STATus Subsystem Questionable Integrity Uncalibrated Register Questionable Integrity Uncalibrated Condition :STATus:QUEStionable:INTegrity:UNCalibrated:CONDition? This query returns the decimal value of the sum of the bits in the Questionable Integrity Uncalibrated Condition register. The data in this register is continuously updated and reflects the NOTE current conditions.
Page 383: Questionable Power Register
Using the STATus System STATus Subsystem Questionable Integrity Uncalibrated Negative Transition :STATus:QUEStionable:INTegrity:UNCalibrated:NTRansition <number> :STATus:QUEStionable:INTegrity:UNCalibrated:NTRansition? This command determines which bits in the Questionable Integrity Uncalibrated Condition register will set the corresponding bit in the Questionable Integrity Uncalibrated Event register when the condition register bit has a negative transition (1 to 0).
Page 384 Using the STATus System STATus Subsystem Questionable Power Enable :STATus:QUEStionable:POWer:ENABle <number> :STATus:QUEStionable:POWer:ENABle? This command determines which bits in the Questionable Power Condition Register will set bits in the Questionable Power Event register, which also sets the Power Summary bit (bit 3) in the Questionable Register.
Page 385: Questionable Temperature Register
Using the STATus System STATus Subsystem Questionable Power Positive Transition :STATus:QUEStionable:POWer:PTRansition <number> :STATus:QUEStionable:POWer:PTRansition?> This command determines which bits in the Questionable Power Condition register will set the corresponding bit in the Questionable Power Event register when the condition register bit has a positive transition (0 to 1).
Page 386 Using the STATus System STATus Subsystem Questionable Temperature Event Query :STATus:QUEStionable:TEMPerature[:EVENt]? This query returns the decimal value of the sum of the bits in the Questionable Temperature Event register. The register requires that the associated PTR or NTR filters be set NOTE before a condition register bit can set a bit in the event register.
