2-13 Connector Care Quick Start Guide
2-28 PN: 10580-00305 Rev. L MS20xxC UG
GPS Antenna Connector
This GPS antenna connection is for GPS only (Option 31 only). Refer to Figure 2-13, item “2”
on page 2-20.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
SMA connector. Do not over tighten the connector. The recommended torque is 8 lbf·in
(0.9 N·m or 90 N·cm).
Reference Output, 10 MHz (50 ohm)
This port is present only on MS203xC instrument models. The SMA female connector (see
Figure 2-14, item “3” on page 2-21 ) provides an output to the internally generated 10 MHz
reference signal.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
SMA connector. Do not over tighten the connector. The recommended torque is 8 lbf·in
(0.9 N·m or 90 N·cm).
Spectrum Analyzer RF In (50 ohm)
This port is present only on MS203xC instrument models (see Figure 2-14, item “4” on
page 2-21). It provides the input 50 ohm interface for the Spectrum Analyzer function.
Maximum input is +30 dBm at ±50 VDC.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
Type-N connector. Do not over tighten the connector. The recommended torque is 12 lbf·in to
15 lbf·in (1.36 N·m to 1.70 N·m).
Type K Connectors (Option 11) for RF In Port
The K connector option configures the VNA Master with K connectors at the Spectrum
Analyzer RF In port and at the VNA Ports.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
K connector. Do not over tighten the connector. The recommended torque is 8 lbf·in (0.9 N·m
or 90 N·cm).
Note
The GPS antenna connection on the VNA Master is fitted with an SMA connector.
A DC voltage (3.3 V or 5.0 V) is present on this connector to support active GPS
antennas. Connect only supported antennas, such as the Anritsu GPS antenna
(part number 2000-1528-R) to this port.
