Page 49: Externally Leveling The Swept Cw Generator
In externally leveled operations, the output power from the swept CW generator is detected by an external sensor. The output of this detector is returned to the leveling circuitry, and the output power is automatically adjusted to keep power constant at the point of detection.
Page 50 Note Figure 1-12 shows the input power versus output voltage characteristics for typical HP diode detectors. From the chart, the leveled power at the diode detector input resulting from any external level voltage setting may be determined. The range of power adjustment is approximately -30 dBm to +18 dBm.

Page 58: Working With Spectrum Analyzers/Reverse Power Effects
Reverse power is a problem with spectrum analyzers that do not have preselection capability. Some analyzers have as much as frequencies. The effects of reverse power are less in the heterodyne band (0.01 to 2.0 GHz) where the power amplifier provides some broadband matching.
Page 59: Optimizing Swept Cw Generator Performance
There are two basic front-panel methods of creating a flatness correction array. The first and quickest method is to use an HP 437B power meter. Refer to Figure 1-18 for the setup. The second method is just as accurate, but requires a little more interaction between the operator and the instruments.
Page 60: Creating A User Flatness Array Automatically, Example 1
Creating a User Flatness Array Automatically, Example 1 In this example, a flatness array containing correction frequencies from 4 to 10 GHz at 1 GHz intervals is created. An HP 438B power meter controlled by the swept CW generator through the interface is used to enter the correction data into the flatness array.
Page 61 If an HP-IB error message is displayed, verify that the interface connections are correct. Check the HP-IB address of the power meter and ensure that it is the same address the swept CW generator is using (address 13 is assumed).
Page 62: Creating A User Flatness Array, Example 2
Creating a User Flatness Array, Example 2 This example shows how to use the swept CW generator and a power meter in manual entry mode. This example also introduces two features of the swept CW generator. The softkey Freq Follow simplifies the data entry process and the softkey List Mode sets up a list of arbitrary test frequencies.

Related statements used by some computers: RESUME Clear Clear causes all HP-IB instruments, or addressed instruments, to assume a “cleared” condition, with the definition of “cleared” being unique for each device. For the swept CW generator: 1. All pending output-parameter operations are halted.
Page 86 Some BASIC examples: CLEAR 7 to clear all HP-IB instruments, or CLEAR 719 to clear an addressed instrument. Related statements used by some computers: RESET CONTROL SEND The preceding statements are primarily management commands that do not incorporate programming codes. The following two statements do incorporate programming codes, and are used for data communication.
Page 87: Output
A BASIC example: 100 OUTPUT719; “programming codes” The many programming codes for the swept CW generator are listed in the “SCPI Command Summary” in Chapter 2. Related statements used by some computers: CONTROL CONVERT IMAGE IOBUFFER TRANSFER Enter Enter is the complement of OUTPUT, and is used to transfer data from the addressed instrument to the controller.
Page 88 ASCII CR (carriage return), comma, or semicolon might cause a false termination. Suppression of the EOL causes the computer to accept all bit patterns as data, not commands, and relies on the HP-IB EOI (end or identify) line for correct end-of-data termination.
Page 89: Getting Started With Scpi
An instrument is any device that implements SCPI. Most instruments are electronic measurement or stimulus devices, but this is not a requirement. Similarly, most instruments use an HP-IB interface for communication. The same concepts apply regardless of the instrument function or the type of interface used.
