  • Page 32 Performing Fundamental Synthesizer Op- erations This chapter describes fundamental synthesizer operations. The purpose of this chapter is to familiarize you with the fundamental operation of the synthesizer. Procedures cover how to enter or modify data, how to set the HP-IB address, how to save and recall instrument states, etc. N O T E This product has been designed and tested in accordance with IEC Publication 1010, Safety Requirements for Electronic Measuring Apparatus, and has been supplied in a safe condition.
  • Page 33 To Enter Data with the Numeric Keypad The synthesizer numeric keypad and units terminator keys provide one way to enter function parameters. Select the desired function key or shifted function key. The function must have a numeric value (parameter) associated with it in order to enter a new value with the numeric keypad.
  • Page 34 To Modify Data with the Knob The knob on the synthesizer front panel is used to modify data. You turn the knob in order to increase or decrease the parameter value of the currently active function. Additionally, you can modify the position of the cursor ( that is over the active parameter in order to increase or decrease the rate at which the function parameter changes.
  • Page 35 Performing Fundamental Synthesizer Operations To Modify Data with the Knob Continue to press the key until the cursor is positioned over the desired digit. For example, suppose that frequency is the current active parameter, and you wish to change the cursor position from 1 MHz to 1 GHz. The steps that follow illustrate how to accomplish this: a.
  • Page 36 To Modify Data with the Arrow Keys The synthesizer (arrow) keys increase or decrease the value of the currently active parameter by an amount set with the key. The STEP SIZE amount set with the key is referred to as the increment value. STEP SIZE Select the function key of the parameter to be modi ed.
  • Page 37 Performing Fundamental Synthesizer Operations To Modify Data with the Arrow Keys c. Terminate the frequency increment value entry by pressing the key. When either the key is pressed, the frequency will be either increased or decreased by 250 MHz instead of 100 MHz. N O T E The knob and keys operate independently of each other.

  • Page 59 Generating Signals with the Synthesizer To Use External Power Meter Leveling When the range hold meter value is terminated, the synthesizer enters the external power meter leveling mode. Power is then held at a constant level at the sampling point, regardless of gain changes in the signal path between the synthesizer RF OUTPUT connector and the sampling point.
  • Page 60 To Use the Level Correct Routine When activated, the level correct function adjusts the synthesizer output power (to compensate for losses or gains) to provide constant, leveled power at output of the external signal path. When the level correct routine is used, the synthesizer performs a calibration process that corrects for external losses or power variations in an external signal path.

  • Page 61: Level Correct Routine Equipment Setup

    Generating Signals with the Synthesizer To Use the Level Correct Routine In addition, you must supply the cables and adapters necessary to connect the equipment. Connect the equipment as shown in Figure 3-4: Figure 3-4. Level Correct Routine Equipment Setup Set the address that the synthesizer will use to address the power meter during the level correct routine.
  • Page 62 Generating Signals with the Synthesizer To Use the Level Correct Routine d. Press the key until the display reads POWER METER IS HP437B . Press the key. POWER LEVEL Adjust the power level to a level near the center of the power sensor range.
  • Page 63 Generating Signals with the Synthesizer To Use the Level Correct Routine Note that the level correct stop frequency remains on the display after it is terminated so that it can be modi ed using the knob or keys if desired. Press the (ENTER) key to begin the number of points entry.
  • Page 64 Generating Signals with the Synthesizer To Use the Level Correct Routine N O T E As the routine is running, the synthesizer sends the power meter each frequency point so that the correct calibration factor at each frequency can be used. For best accuracy, the correct calibration factors for the power sensor being used should be entered into the power meter prior to running the level correct routine.
  • Page 65 Generating Signals with the Synthesizer To Use the Level Correct Routine To store the table of level correct values in a level correction register location, perform the following procedure. Press the key and then the (SAVE CR) key. SHIFT INT LEVEL The display will show SAVE IN TABLE XXX where XXX is the current level correction register number.
  • Page 66 To Use Previously Stored Level Correct Data When the level correct routine is run, the synthesizer creates a table of correction values for each frequency point in the table. Up to four level correction tables can be stored in the synthesizer memory. If the current signal path at the synthesizer output (the external signal path) is identical to the external signal path on which a level correct routine had been previously run, the level correction table can be recalled from memory and be used at a...
