System Commands

System Commands

System commands control system functions that are not directly related to output control, measurement, or status functions. Common commands are also used to control system functions.

SYSTem:COMMunicate:RLSTate LOCalREMoteRWLock

SYSTem:COMMunicate:RLSTate?

This command configures the remote/local state of the instrument according to the following settings.

LOCal The instrument is set to front panel control (front panel keys are active). REMote The instrument is set to remote interface control (front panel keys are active).

RWLock The front panel keys are disabled (the instrument can only be controlled via the remote interface).

The remote/local state can also be set by interface commands over the GPIB and some other I/O interfaces. When multiple remote programming interfaces are active, the interface with the most recently changed remote/local state determines the instrument’s remote/local state.

The remote/local state is unaffected by *RST or any SCPI commands other than SYSTem:COMMunicate:RLState. At power-on however, the communications setting always returns to LOCal.

SYSTem:ERRor?

This query returns the next error number and its corresponding message string from the error queue. The queue is a FIFO (first-in, first-out) buffer that stores errors as they occur. As it is read, each error is removed from the queue. When all errors have been read, the query returns 0, NO ERROR. If more errors are accumulated than the queue can hold, the last error in the queue will be -350, TOO MANY ERRORS (see Appendix C for error codes).

SYSTem:VERSion?

This query returns the SCPI version number to which the instrument complies. The returned value is of the form YYYY.V, where YYYY represents the year and V is the revision number for that year.

*IDN?

This query requests the power supply to identify itself. It returns a string of four fields separated by commas.

With outputs ranging from 0 to 60 V and up to 6 A, the N5700 series caters to both low and high-power applications effectively.

A notable technology integrated into the N5700 series is its advanced measurement capabilities. The built-in voltmeter and ammeter enable real-time monitoring of output voltage and current, ensuring precise control over the power supplied to the device under test. This feature is particularly advantageous in troubleshooting and optimization scenarios, providing engineers with immediate feedback on performance.

The N5700 also embraces the latest in power supply control technology with its intuitive user interface. The front panel incorporates a clear display and simple navigation controls, allowing users to program settings easily and access functions without extensive training. Additionally, remote programming capabilities via GPIB, USB, or LAN facilitate integration into automated test setups, enhancing productivity and efficiency.

Thermal management is another hallmark of the N5700 series. Its design ensures effective heat dissipation, enabling reliable operation even under demanding conditions. This robustness is critical in environments where consistent performance is essential, such as in research laboratories and manufacturing facilities.

Furthermore, safety features are thoughtfully included in the N5700 series, such as overvoltage protection, overcurrent protection, and short-circuit protection. These elements assure users that their devices and test setups remain secure during testing, minimizing the risk of damage.

In summary, the Agilent N5700 series power supplies encapsulate the fusion of precision, advanced measurement technology, user-friendly design, thermal management, and robust safety features. This combination makes them an invaluable tool for engineers and researchers engaged in electronic testing and development across various industries. With its versatility and reliability, the N5700 series continues to play a pivotal role in advancing electronic measurement methodologies.
