Page 242: Sending Scpi Command Messages
Overview of Remote Control Sending SCPI command messages Sending SCPI command messages Types and structure of commands The SCPI commands available for the E4980A/AL are classified into two groups as follows. E4980A/AL commands Commands specific to the E4980A/AL. They cover all measurement functions that the E4980A/AL has and some general-purpose functions.
Page 243: Grammar Of Messages
HTBasic automatically sends the message terminator after the last data byte. Parameters A space (ASCII code: 32) is required between a command and its first parameter. When sending several parameters in a single command, separate each parameter with a comma (,). Keysight E4980A/AL Precision LCR Meter...
Page 244: Remote Mode
Press [Local/Lock] to cancel the remote mode. When the E4980A/AL enters a local lockout state by sending the LOCAL LOCK BUS command from the controller, you cannot unlock the remote mode even if you press [Local/Lock]. (Only RMT is displayed in the status display area, so you cannot distinguish the local lockout state from a normal remote mode.)
Page 245: Trigger System
“Measurement” and “Waiting for Trigger” states. • :ABOR • *RST • Other commands to change settings (:FREQ, etc.) When the DC bias function is turned on, the trigger system switches to the “Idle” state. Keysight E4980A/AL Precision LCR Meter...
Page 246 (MAN), the trigger system automatically switches from the “Idle” state to the “Waiting for Trigger” state. The E4980A/AL in the “Idle” state switches to the “Measurement” state by using the :TRIG command. When the :ABOR command is executed, the trigger system switches to the “Idle”...
Page 247 1. :TRIG GPIB command When the trigger system is either in the “Waiting for Trigger” or “Idle” state, the E4980A/AL is triggered by sending the :TRIG command. When reading measurement results via a controller in the “Idle” state, you need to use the :FETch? query command.
Page 248 Overview of Remote Control Trigger System In the “Waiting for Trigger” state, the E4980A/AL is triggered by sending the *TRG command or the TRIGGER (GET) bus command, and measurement results in one trigger sequence can be read without sending the :FETCh? query command in the “Idle” state.
Page 249 Overview of Remote Control Trigger System Figure 8-14 Trigger system and data transfer (INT/MAN) Keysight E4980A/AL Precision LCR Meter...
Page 250 Figure 8-15 Trigger system and data transfer (EXT/BUS) When the E4980A/AL is set to the external trigger mode, and is triggered via the external trigger input terminal or an optional interface, this trigger signal has the same effect as the :TRIG command.
Page 251: Data Buffer Memory
Data Buffer Memory Data Buffer Memory The E4980A/AL has a data buffer memory function. The data buffer memory can hold up to 201 sets of measurement results, and all buffered measurement results are transferred at once to the controller by using the :MEM:READ? DBUF command.
Page 252: When Data Buffer Memory Is Used
Therefore, you do not have to clear the output buffer after each measurement. *When the E4980A/AL is triggered using the *TRG or TRIGGER (GET) bus command, the measurement results are stored in both the data buffer memory and the output buffer.
Page 253 Overview of Remote Control Data Buffer Memory same and are adjacent, the E4980A/AL measures the device once, but the number of data sets stored in the data buffer memory is equal to that of the sweep points. When the list sweep measurement’s limit function is set to off at a sweep point, IN/OUT is 0.
Page 254: Output Format Of Data Buffer Memory
The data format and meaning of <DATA A>, <DATA B>, <STATUS>, <BIN No.>, or <IN/OUT> are the same as those of the BINARY data format described in Data Format of “Data Transfer” on page 260 Keysight E4980A/AL Precision LCR Meter...
Page 255 Binary format (Buffer memory) NL^END is not included in the number of bytes to transfer. For example, the number of byte of “:MEM:DIM DBUF, 3”, is (8  4)  3 + 1 = 97 bytes. Keysight E4980A/AL Precision LCR Meter...
Page 256: Starting A Measurement Cycle (Triggering The Instrument)
Trigger the instrument to start measurement when the trigger system is in the “Waiting for Trigger” state Put the E4980A/AL in the “Waiting for Trigger” state and start measurement whenever you want. In cases where it takes some time to obtain stable measurement values, a controller can control the timing for triggering.
Page 257 Use the :LIST:MODE SEQ|STEP command to change the list sweep mode. 1. Sequential mode When the E4980A/AL is triggered once, the device is measured at all sweep points. 2. Step mode The sweep point is incremented each time the E4980A/AL is triggered.
Page 258: Waiting For The End Of Measurement
:STAT:OPER:ENAB Follow these steps to use an SRQ. Step 1. Configure the E4980A/AL so that it generates an SRQ when the operation status event register’s bit (a bit that is set to 1 during measurement) is changed from 1 to 0.

Page 260: Data Transfer
Data Transfer Data Transfer This section describes data transfer. Data Format The E4980A/AL offers two data formats for GPIB data transfer to the controller, ASCII and BINARY. Data transfer rates vary depending on the data format used. ASCII Format The ASCII data format is the default output format. When the :FORM:DATA ASC command is executed, the E4980A/AL transfers data in the ASCII format.
Page 261 The <BIN No.> data is output with the measurement data only when the comparator function is set to on. The data output formats for <BIN No.> uses a two- or three-ASCII character data-length format as follows. SN or SNN (S:+/-, N: 0 to 9) Keysight E4980A/AL Precision LCR Meter...
Page 262 When the comparator function of the list sweep measurement is not used, the <IN/OUT> data output result is 0 (zero). The data output formats for <IN/OUT> use the two-ASCII character fixed-length format as follows. (S:+/-, N: 0 to 1) Keysight E4980A/AL Precision LCR Meter...
Page 263 Overview of Remote Control Data Transfer BINARY Format When the :FORM:DATA REAL,64 command is executed, the E4980A/AL transfers data in the BINARY format. This BINARY format is the 64-bit floating point binary format specified in IEEE Standard 754-1985. The BINARY data output format on the MEAS DISPALY, BIN No, or BIN COUNT page is shown below.
Page 264 RN = 0 For example, S = 1 EXP = 0111111 1111 (1023) 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (251)  RN = (-1)1  2(1023 - 1023)  {1 + (251 / 252)} = -1  1  1.5 = -1.5 Keysight E4980A/AL Precision LCR Meter...
Page 265 <DATA A>, <DATA B>, <STATUS>, and <IN/OUT> are repeated as many times as there are sweep points. Each data format is the same as the 8-byte data format described previously. Figure 8-25 Binary Format 2 (List sweep) Keysight E4980A/AL Precision LCR Meter...

Page 268: Enabling The Status Byte
Bit 6 (RQS) is non-maskable, and bits 0 to 3 are always 0 (zero). Thus, it is meaningless to mask these bits. (The *SRE command’s bit pattern for masking bit 6 is ignored, while the *SRE command’s bit pattern for masking bits 0 to 6 is accepted, but is meaningless.) Keysight E4980A/AL Precision LCR Meter...
Page 269: Operation Status Register Structure
The structure of the operation status register group is shown in Figure 8-28 below. This group consists of the following three registers. • Operation status condition register • Operation status event register • Operation status event enable register Figure 8-27 Operation Status Register Structure Keysight E4980A/AL Precision LCR Meter...
Page 270 The operation status condition register consists of 16 bits, and reflects these states in its condition bits. Therefore, each time the E4980A/AL’s condition is changed, its condition bit changes from “0” to “1,” or from “1” to “0.” Table 8-2 below shows each bit of the operation status condition register.
Page 271 The default setting is :STAT:OPER:ENAB 0 (all bits of the operation status event register are disabled). Bit 1, bit 2, and bits 5 to 15 are always 0 (zero). Thus, it is meaningless to mask them. Keysight E4980A/AL Precision LCR Meter...
Page 272: Standard Event Status Register
-100 to -199 When you read the contents of the standard event status register using the *ESR? query command, the standard event status register is cleared, and bit 5 of the status byte is reset to “0.” Keysight E4980A/AL Precision LCR Meter...

Page 448: Product Overview
Product Overview 42841A Bias Current Source The 42841A is a DC bias current source for use with the E4980A/AL (with Option 002 Bias Current Interface). All measurement setups, including the DC current bias, can be set from the E4980A/AL front panel.
Page 449: Specifications When Measuring With The 42841A
DC bias signal current level when the 42841A is connected. The measurement accuracy (typical) when connecting the E4980A/AL to the 42841A is the same as that when connecting the 4284A to the 42841A, described in the Specifications of the 42841A manual. When test frequency exceeds 1 MHz (the highest value in the 42841A manual), we assume an accuracy that is double the accuracy at 1 MHz test frequency.
Page 450: Preparation
Equipment Requirements The 42841A supplies 20 A (1 unit) and 40 A (2 units) DC current bias when combining the E4980A/AL (test frequency: 20 Hz to 2 MHz) and the 42842A/B test fixture. The following equipment is necessary for a system that uses the E4980A/AL and the bias current source.
