Starting a Measurement (Trigger) and Detecting the Completion of a Measurement (End of Sweeps) This chapter describes how to generate a trigger to start a measurement and how to detect the completion of a measurement.
Page 72: Triggering A Measurement (Starting A Measurement)
(End of Sweeps) Triggering a Measurement (Starting a Measurement) Triggering a Measurement (Starting a Measurement) Trigger system The trigger system of the Agilent 4294A has three states: “Idle,” “Waiting for Trigger,” and “Measurement” as shown in Figure 5-1. Figure 5-1 Trigger system The state transitions in the trigger system are described below.

Starting a Measurement (Trigger) and Detecting the Completion of a Measurement (End of Sweeps) Triggering a Measurement (Starting a Measurement) Trigger source setting Method of generating a trigger Internal trigger (INT) Automatically generates an internal trigger. External trigger (EXT) Enters a trigger signal from the EXT TRIGGER terminal on the rear panel to generate a trigger.
Page 74: Waiting For The Completion Of One Or More Sweeps (Detecting The Completion Of A Measurement)
“ESNB” on page 314 The procedure is as follows: Step 1. Make the setting so that the Agilent 4294A generates an SRQ when the sweep completion bit in the instrument event status register is set to “1.” Step 2. Generate a trigger to start one or more sweeps.

Page 76: Using The *Opc? Command
You can use a setting to make the controller wait for the completion of one or more sweeps performed by the Agilent 4294A (for example, using the WAIT command of HP BASIC). This method is simple, but if you set an inappropriate wait, unexpected errors could occur.
Page 77: Reading/Writing Measurement Data
Reading/Writing Measurement Data This chapter describes how to read and write measurement data and how to obtain level monitoring and limit test results.
Page 78: Data Transfer Format
Data Transfer Format The format applicable when you read measurement parameter settings from the Agilent 4294A (as when you read the sweep start point with “STAR?”) is the ASCII format, regardless of which data transfer format has been specified. You can select either the ASCII format (default) or one of the binary formats for reading measurement data, waveform analysis results and so on from the Agilent 4294A (as when you read a data trace array with “OUTPDTRC?”).

Processing Measurement Results Reading Measurement Data at Specific Measurement Points (Using the Marker Function) Reading Measurement Data at Specific Measurement Points (Using the Marker Function) You can use the marker to read measurement data at specific points on the trace or search for the point that meets a specific condition such as the maximum value.

Page 98: Reading The Marker-Specified Value
*1.You can read parameter values only when you use the fixed Δ marker. You can use the following command to display a list of all marker-specified values on the Agilent 4294A LCD. Note, however, that you cannot use these commands to read these values.

Use the following command to turn this function ON or OFF. • “MEASTAT” on page 349 NOTE The statistics analysis function is available when the marker function is ON.
Page 103: Bandwidth Analysis
Normally, trace bandwidth analysis is made when the marker searches for peaks. Therefore, the above values appear to the right of “Peak:” on the Agilent 4294A display. However, if the marker is not positioned at any of the peaks, the above values do not represent parameter values obtained at a peak.

Page 132: Using The Status Register
“*ESE” on page 258 Here described is how to work with SRQ in your program. Step 1. Set the 4294A to generate SRQ when “1” is assigned to the each error occurrence bit of the standard event status register. Step 2. Perform an interruption processing at the time SRQ is generated.

This program performs necessary settings for SRQ, intentionally sends a command that the 4294A does not support to cause an error, then handles the error occurred. In the error handling, the error is identified, its error number and message are displayed followed by a message showing that the program is aborted.

The steps to use the program are described below: Step 1. Connect the 16451B dielectric test fixture to the 4294A, and start this program. When the message “Which electrode of 16451B is used? 0:A, 1:B, 2:C, 3:D” is displayed, select the electrodes you want to use by specifying the corresponding number (0 to 3).

Application Sample Programs Measuring Magnetic Materials Measuring Magnetic Materials This section describes how to measure magnetic materials using the 4294A (and the 42942A terminal adapter) and the 16454A magnetic material test fixture. Measurement Procedure Figure 13-2 shows the flow of magnetic material measurement.
Page 214 Application Sample Programs Measuring Magnetic Materials Step 3. Connect the 16454A Connect either the small of large electrode of 16454A (whose size is suitable for the shape of the magnetic material (MUT) you want to measure) to the 42942A. NOTE For details on how to handle the 16454A (the dimensions of the MUT suitable for measurement in each size (small or large)), refer to the 16454A Operation and Service Manual.

Page 501 Program mnemonic too long The length of the header exceeds 12 characters. (Refer to IEEE488.2,7.6.1.4.1.)) -113 Undefined header A header not defied for the 4294A was received. For example, "*XYZ" not defined for the 4294A was received. -114 Headers Suffix out of range The suffix of the header is out of range.
Page 502 Character data not allowed A character data element (that did not violate the standard) was received at where the 4294A did not accept any character data elements. For example, a parameter must be enclosed with double quotation marks (") but they are missing.
Page 503 (Refer to IEEE488.2,7.7.5.2.) For example, the END message was received before the end quotation mark character appeared. -158 String data not allowed A string data element was received at where the 4294A did not accept any string data elements. -160 Block data error An error not included in error numbers between -161 and -169 occurred during the syntax analysis of block data.
Page 504 A program data element complying with the syntax standard was analyzed but the 4294A could not execute it at present. -222 Data out of range A data element (that did not violate the standard) out of the range the 4294A defined was received. -223 Too much data...
Page 505 Error messages Error number: -256 correctly. This message is displayed, for example, when you specifies the floppy disk drive as the storage device but no floppy disk is set into the drive (correctly). -256 File name not found The specified filename was not found and, as a result, the command was not executed correctly.
Page 506 -420 Query UNTERMINATED Status that causes an "UNTERMINATED" Query error. (Refer to IEEE488.2,6.3.2.) This error occurs, for example, when the 4294A is specified as a talker and an incomplete program message is received. -430 Query DEADLOCKED Status that causes a "DEADLOCKED"...
