  • Page 48: Power Sweep And Power Slope Operation

    Power Sweep and Power Slope Operation Power Sweep Operation 1-18 Getting Started Basic The power sweep function allows the power output to be swept (positive or negative) when the synthesizer is in the CW frequency mode. The power output of the synthesizer determines the maximum leveled power sweep that can be accomplished.

  • Page 49: Power Slope Operation

    The synthesizer performs a power sweep beginning at -20 dBm and ending at f5 dBm. The power meter indicates +25 dB. Power Slope Operation This function allows for compensation of high frequency system or cable losses by linearly increasing the power output as the frequency increases.

  • Page 53: Externally Leveling The Synthesizer

    Externally Leveling the Synthesizer Leveling with Detectors/Couplers /Splitters In externally leveled operations, the output power from the synthesizer 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 54 Power splitters have a coupling factor of 0 dB. 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 i-18 dBm.

  • Page 56: External Leveling Used With The Optional Step Attenuator

    Hint l-26 Getting Started Advanced External Leveling Used With the Optional Step Attenuator Some external leveling applications require low output power from the synthesizer. The synthesizer automatically uncouples the attenuator from the ALC system for all external leveling points. Press Note the display.

  • Page 57: Leveling With Power Meters

    Leveling with Power Leveling with a power meter is similar to leveling with a diode detector. Figure 1-13 shows the setup for power meter leveling. Meters 1. Set up the equipment as shown. Be sure to set the power meter to 2.

    Leveling with MM-wave Millimeter-wave source module leveling is similar to power meter leveling. The following figures illustrate the setups for leveling with a Source Modules mm-wave source module. SYNTHESIZER Figure 1-14.

  • Page 60: Working With Mixers/Reverse Power Effects

    Working with Mixers/Reverse Power Effects Note I-30 Getting Started Advanced Uncoupled operation applies to Option 001 synthesizers only. Uncoupled operation is useful when working with mixers. Figure 1-16 shows a hypothetical setup where the synthesizer is providing a small signal to a mixer. The synthesizer output is -8 dBm, which in Leveling Node Normal results in ATTEN = 0 dB, ALC Level = -8 dBm.

    Working with Spectrum Analyzers/Reverse Power Effects 1-32 Getting Started Advanced Reverse power is a problem with spectrum analyzers that do not have preselection capability. Some analyzers have as much as +5 dBm LO feedthrough coming out of their RF input, at some frequencies.

  • Page 63: Optimizing Synthesizer 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 64: Creating A User Flatness Array Automatically, Example 1
