Options
Time-domain capability - Option 010
Optional time-domain capability is available with the PNA Series network analyzer.
Time domain is most often used for locating reflections inside anechoic chambers. Time
domain displays reflections versus time or distance inside an anechoic chamber. Know-
ing the distance of a reflection from the source antenna helps the operator locate the
reflection source, and helps to identify and mitigate the reflection. Figure 34 shows the
time-domain response of a compact antenna test range; the various reflection sources
are identified.

Configurable test set - Option 014

PNA E836xC
Provides six front panel access loops. Three access loops are for port one and three for
port two. The loops provide access to the signal path between (a) the source output and
the reference receiver, (b) the source output and directional coupler thru arm and (c)
the coupled arm of the directional coupler and the port receiver. This option improves
instrument sensitivity for measuring low-level signals by allowing the user to bypass the
internal couplers and enter the test signal directly into the receiver port of the analyzer.
(See PNA Series Microwave Data Sheet, literature number 5988-7988EN, for a basic
block diagram.)
Frequency offset - Option 080
1
This option enables the PNA Series microwave network analyzers to set the source
frequency independently from where the receivers are tuned. This ability is useful for
antenna measurements where the measurement system contains remote mixers and for
RCS measurements in pulse mode.
IF access - Option H11 PNA E836xC
Provides IF gating hardware and hardware to enable antenna and broadband millimeter-
wave measurements to 110 GHz. For each of the PNA’s measurement receivers, IF gates
(enabled with pulsed measurement capability, Option 008) and external IF inputs are
added. In addition, access to the PNA’s internal RF and LO source is provided for remote
mixing applications. Option H11 is useful for antenna measurements with external
mixers. Use external IF access for up to 20 dB more sensitivity when making antenna
measurements with a remote mixer configuration. Pulsed antenna applications also
require the Pulse measurement capability (Option 008). Broadband measurements to 110
GHz require an N5260A millimeter-wave test set controller and test heads. Option H11
requires Options 014, 080, 081, and UNL.
