To enable an RS-232 connection 1. After starting the E7501A SCPI interface and selecting either the Agilent E7501A or Demo configuration, select the RS-232 Enable checkbox.
Using SCPI Interfaces Using the E7501A SCPI Interface IP Address The IP address is used to identify a node on a network and to specify routing information. Each node on a network must be assigned a unique IP address. This address is made up of the network ID, plus a unique host ID assigned by the network administrator. This address is typically represented in dotted-decimal notation, with the decimal value of each octet separated by a period (for example, 138.57.7.27).
Using SCPI Interfaces Starting the E7501A SCPI Interface Programmatically Starting the E7501A SCPI Interface Programmatically The E7501A SCPI interface can be started programmatically from a DOS command prompt, a Windows NT shortcut, or from a program using the following syntax: \ScpiClient.
4 Specifications and Characteristics In this chapter, you will learn about: • System Specifications for the Agilent E7501A arbitrary analog signal developer System Specifications refer to the combination of specifications for the Agilent E6432A microwave synthesizer and Racal 3153 arbitrary waveform generator being used. These system specifications describe warranted product performance and apply over the 0 to +55 degrees Celsius temperature range, except as noted otherwise.
Specifications and Characteristics Warm-Up Time Required Warm-up time is required before the system can meet specifications. Operation to specifications requires 30 minutes to warm-up from a cold start at 0 to +55 degrees Celsius. Correctable Values only apply at ± 3 degrees Celsius of the ambient temperature of where a correction is performed.
