To protect your E4990A, follow the instructions below: Read the warning labels and specifications Do not exceed the values provided in the specifications guide or as indicated by the yellow warning labels on the front panel of the E4990A. Refer to the specifications for the conditions required to meet the listed specifications.
Page 22: Install Antivirus Protection
The E4990A does NOT have antivirus protection when shipped. Use of an antivirus program is strongly recommended if you connect the E4990A to the LAN (Internet). In addition, the use of a firewall could help to protect the E4990A from viruses. However, some firewalls could limit DCOM connectivity of the E4990A.

Page 98: Averaging Function
Averaging for Each Measurement Point (Point Averaging) Point averaging averages each data point by a user-specified averaging factor. The Agilent E4990A repeatedly measures the same point until the averaging factor is reached. It then divides the vector summation of the measurement value by the averaging factor and starts measuring the next point.

Single Action (Segment Sweep) Other topics about Setting Measurement Conditions Overview The E4990A has one trigger source. When this trigger source detects a trigger signal that has occurred, a sweep or point measurement is performed for channels. The execution of measurement for each channel does not depend on whether the channel is displayed.
Page 103 Measurement Trigger Function Sources Internal Uses a consecutive signal generated by the (Internal) firmware as a trigger source.

Depending on the system controller and the interface, you can configure 5 types of remote control system as shown in the table below. System controller Interface Overview System to control the E4990A and other devices connected via GPIB from GPIB the external controller. (talker/listener mode)
Page 252 IEEE 488.1, IEC-625, IEEE 488.2, and JIS-C1901. The GPIB interface allows you to control the Agilent E4990A from an external computer. The computer sends commands and instructions to the E4990A and receives data sent from the E4990A via GPIB.
Page 253 Programming While the E4990A is turned OFF, the SRQ status of the E4990A is active. To prevent an incorrect operation on the SRQ of the GPIB remote control system, disconnect the E4990A from the system when the E4990A is turned OFF.

Page 259 3. The telnet screen opens. 4. Type a command and press the return key; it is sent to the E4990A and executed. If you enter a command that queries some data, the query response is displayed below the line you have entered the command.
Page 260 E4990A breaks and telnet ends. Control from a program (using port 5025) When controlling the E4990A from a program on the external controller, use the socket of port 5025 for connection. Some functions such as service requests that are available in the GPIB remote control system are not available in control over telnet server.
Page 261 USB Port Types There are two standard types of USB ports. The external controller (PC) must be connected via the USB host port (type A), while the E4990A and other USB compatible devices must be connected via the USB interface port (type B).
Page 262 Type B: USB (USBTMC) interface port Preparing E4990A You do not have to configure any softkey or command of the E4990A in order to control the E4990A from an external controller. Simply connect a USB cable to the USB interface port.

Page 324 If the bit of the service request enable register is "1," a service request (SRQ) is generated by the positive transition of the corresponding status byte register bit. By generating SRQ, you can notify the controller that the E4990A is requesting service. In other words, interruption by SRQ can be programmed. Event Register Reflects the corresponding condition of the E4990A (e.g., occurrence of an...

Page 665 This command sets/gets the effective scope of triggering. When this function is enabled with a value of "ACTive", only active channel is triggered. When this function is enabled with a value of "ALL", all channels of the E4990A are triggered. For example, if TRIGger.SCOPe value is "ACTive" when :INIT:CONT command is turned ON for all channels, a measurement channel will automatically be changed by switching over the active channel.
Page 666 E4990A Help This command generates a trigger immediately and executes a measurement, regardless of the setting of the trigger mode. This command is different from :TRIG as the execution of the object finishes when the measurement (all of the sweep) initiated with this object is complete.
