Performance Verification for N7000-Series Probes
Bandwidth Performance Verification
This procedure documents the bandwidth performance of the N7003A InfiniiMax
III+ probe amplifier with the N2836A solder-in probe head.
Equipment Needed
• InfiniiMax III+ N2836A solder-in probe head.
• Keysight 2 port E8361A/C Vector Network Analyzer or equivalent VNA that
covers at least a 50 MHz to 20 GHz range. The VNA must have the following
capability:
• Ability to use a Touchstone file to de-embed at a port.
• A bias port for port 1 of the VNA. That is it must have an internal bias T’s and
a BNC port that allows bias to be applied to port 1.
• 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.
• Proper test port cables, with adapters as needed, to provide male 2.92 mm
connectors at reference planes. If 2.4 mm or 1.85 mm test port cables are used,
the following Keysight adapters can be used to convert to 2.92 mm male
connectors:
11904A . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.4 mm (m) to 2.92 mm (m)
11904D. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.4 mm (f) to 2.92 mm (m)
• Keysight N5443A Performance Verification (PV) Fixture. The N5443A includes
an APC 3.5 (f-f) adapter (1250-1749).
• 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 adapter to a
2.4 mm or 1.85 mm VNA calibration load with required return loss could be
used.
• Keysight N5477A AutoProbe II to 3.5 mm (f) Adapter. The N5477A comes with
a required NMD 3.5 mm (m) to 3.5 mm (f) adapter (5062-1247).
• Keysight 1143A Probe Offset Control and Power Module.
• BNC 50 ohm male terminator. Or equivalent; not a critical part. For example, a
Pomona number 3840-50 or 4119-50.
NOTE
The recommended test interval is one year/2000 hours.
NOTE
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.
