Keysight 41800A Operation Note

29 Operation Typical Measurement Setups Using Two 41800As Figure 3-10 shows a typical measurement setup for the network measurements using two probes. Place the probe tip as close to the input of the device under test, and perform a normalize (through) calibration to compensate the frequency response error. Figure 3-10 Network Measurement Setup Example (Using Two 41800As) ...

55 Service Disassembly Disassembly This paragraph describes the procedures for removing the Amplifier/Regulator Board Assembly (PN 41800-66502), and the PC Board/Heatsink Assembly (PN 41800-60005). Removing the Amplifier/Regulator Board Assembly requires removing the labels on the 41800A. The labels will be damaged when you remove them. Use new labels after reassembling the 41800A (you must order the labels). Amplifier/Regulator Board Assembly Removal 1.
