This section documents the bandwidth performance of the N2803A
InfiniiMax III Probe Amplifier with the N5439A ZIF probe head and N5440A
ceramic ZIF tip or with the N5445A browser probe head.
Keysight recommends a test interval of one year or 2000 hours of
operation.
• Keysight 2 port E8361A/C Vector Network Analyzer:
• Or equivalent VNA that covers at least a 50 MHz to 34 GHz range.
This procedure is written assuming the E8361A/C PNA. If a different
VNA is used, references that are specific to the PNA will need to be
modified.
• Needs proper test port cables and/or adaptors to provide male
2.92 mm connectors at reference planes. If test port cables are
2.4 mm or 1.85 mm cables, then Keysight 11904A and 11904D
adaptors can be used to convert to 2.92 mm male connectors.
• Needs to be capable of using a Touchstone file to de-embed at a
port.
• Needs to have bias port for port 1 of the VNA (i.e. has internal bias
T's and a BNC port that allows bias to be applied to port 1)
• Keysight N5443A Performance Verification Fixture.
• Maury Microwave 8775B2 2.92 mm male broadband load.
Or other 2.92 mm male load with similar or better return loss.
A high quality 2.92 mm adaptor to a 2.4 mm or 1.85 mm VNA
calibration load with required return loss could be used.
• Keysight N5477A Autoprobe II/3.5 mm Adaptor.
• Keysight 1143A Power supply.
• Keysight 5062-1247 outside thread 3.5 mm (male) to 3.5 mm (female)
adaptor.
• Keysight N4692A-00F 2.92 mm (female/female) ECal module:
• Or other 2.92 mm calibration kit that can calibrate to the 2.92 mm
male connectors at the test ports.
• BNC 50 ohm male terminator:
Or equivalent; not a critical part
• Example: Pomona number 3840-50 or 4119-50.
• InfiniiMax III Probe Head
• Either the N5439A ZIF probe head with the N5440A ceramic ZIF
probe tip or the N5445A browser probe head.
• Power level: -6 dBm.
• Sweep: Log Frequency 50 MHz to 34 GHz, 284 points
(100 pts/decade).
