This section provides quick tips for performing the following functions:

Extending the RF Frequency Range (3.6 GHz to 50 GHz)

To extend the frequency range to 50 GHz (when option M9365A-FRX is installed), it
is recommended to use the M9169E Programmable Attenuator module to provide
range control and automated field alignments and self-test. The RF signal is
applied to the Aux 2 In connector on the M9365A Downconverter directly or
through the M9169E Programmable Attenuator. For the prerequisites and setup
information for these configurations, refer to the
When writing programs for extended frequency range, use the following option
string in the
DriverSetup= Aux2In=true
This option string is used when the input signal is directly applied to the Aux 2 In
connector. When using M9169E to apply the adjusted input to the Aux 2 In
connector, do not specify the above option string. The resource description in the
Initialize()
automatically takes into consideration the use of Aux 2 In connector.

Attaining Higher IF Bandwidths Using a Wideband Digitizer

To achieve wideband IF, the IF Conditioning/Filtering path in the M9365A
Downconverter module is bypassed and an external digitizer, such as M9202A or
M9703A is used to sample the signal with wider IF bandwidth. The M9393A-WB1
option must be installed to achieve this functionality. For more information on
setup and cabling, refer to the
When writing programs for the above configuration, use the following option string
in the
DriverSetup= ExternalDigitizer=true

signal path of the M9365A Downconverter module. This allows a wide IF
bandwidth. By default, this property is set to false. However, when the
