  • Page 152 ® Remote Control Basics R&S NRPxxS(N) Remote Control Interfaces and Protocols Besides USBTMC, the NRP legacy protocol is available to ensure the compatibility of the R&S NRPxxS(N) power sensors with the R&S NRP‑Z series of power sensors. The usage of this protocol is not recommended for new applications. The resource string represents an addressing scheme that is used to establish a com- munication session with the sensor.
  • Page 153 ® Remote Control Basics R&S NRPxxS(N) Remote Control Interfaces and Protocols For remote control via a network, the computer and the power sensor must be connec- ted via the Ethernet interface to a common network with TCP/IP network protocol. The TCP/IP network protocol and the associated network services are preconfigured on the power sensor.

    ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure ● Supports simultaneous access of multiple users by providing versatile locking mechanisms ● Usable for IPv6 or IPv4 networks The HiSLIP data is sent to the device using the "fire and forget" method with immediate return.
  • Page 156 ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure 11.2.1 Syntax for Common Commands Common (=device-independent) commands consist of a header preceded by an aster- isk (*) and possibly one or more parameters. Examples: *RST RESET Resets the instrument. *ESE EVENT STATUS ENABLE Sets the bits of the event status enable registers.
  • Page 157 ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure Optional mnemonics Some command systems permit certain mnemonics to be inserted into the header or omitted. These mnemonics are marked by square brackets in the description. The instrument must recognize the long command to comply with the SCPI standard. Some commands are considerably shortened by these optional mnemonics.
  • Page 158 ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure Numeric values Numeric values can be entered in any form, i.e. with sign, decimal point and exponent. Values exceeding the resolution of the instrument are rounded up or down. The man- tissa can comprise up to 255 characters, the exponent must lie inside the value range -32000 to 32000.
  • Page 159 ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure Boolean Parameters Boolean parameters represent two states. The "ON" state (logically true) is represen- ted by "ON" or a numeric value 1. The "OFF" state (logically untrue) is represented by "OFF" or the numeric value 0. The numeric values are provided as the response for a query.
  • Page 160 ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure Example: SYSTem:HELP:SYNTax:ALL? Response: #45168xxxxxxxx The ASCII character # introduces the data block. The next number indicates how many of the following digits describe the length of the data block. In the example, the 4 fol- lowing digits indicate the length to be 5168 bytes.
  • Page 161 ® Remote Control Basics R&S NRPxxS(N) SCPI Command Structure Several commands in a command line must be separated by a semicolon ";". If the next command belongs to a different command system, the semicolon is followed by a colon. If the successive commands belong to the same system, having one or several levels in common, the command line can be abbreviated.

    ® Remote Control Basics R&S NRPxxS(N) Status Reporting System Response: INT 11.3 Status Reporting System The status reporting system stores all information on the current operating state of the power sensor, and on errors which have occurred. This information is stored in the sta- tus registers and in the error queue.
