Communication system maintenance and repair often require a technician to trouble-
shoot in bright daylight or in the darkness of night. The light sensor on the front panel of
the N934xC HSA senses the ambient light and automatically adjusts the brightness of
the display and the back-lit keys.
The user can also manually set the brightness of the display, and the brightness of the
back-lit keys, so they can be seen clearly even in any light. The duration of the key light is
settable to provide maximum battery life.

Instructions for HSA Keystrokes for HSA
Switch the screen brightness state from automatic to manual [Shift], [System], {Screen Setting}, {Brightness (Man)}
Rotate the knob to adjust the display brightness

The key measurement setup parameters of a spectrum analyzer are:
– Frequency
Adjust the frequency range measured
– Span
Adjust how closely you look at the signal
– Amplitude
Adjust the view of the signal’s level
A typical spectrum analyzer measurement procedure contains the following three steps:
1. Tune the center frequency of the analyzer to the signal of interest.
2. Adjust the span to zoom in on the signal of interest.
3. Adjust the amplitude to give the optimum view of the signal.
In this demonstration, we will set signal generator to output a signal to N934xC HSA with
an RF cable and set these parameters.

The N934xC HSAs let you save the state, trace data, measurement
results (peak and marker table), limit lines, and screen captures to an
internal le, a USB drive, or remotely via LAN or USB.
The N934xC HSAs provide a dedicated Save button to let you save a
le quickly with a single button press. When the Save button is used,
you can choose to name the le by yourself, or let the HSA automati-
cally pick a le name that consists of a prex (N934xC is the default
but can be edited) and a index.
Another unique feature on the N934xC HSAs is the User key, which
provides a quick way to set up the instrument. You can select from
7 predened instrument setups with a single button push.

Figure 4. GPS information
Instructions for HSA Keystrokes for HSA
In order to receive a GPS signal, you need to move to an open space to
use the internal GPS antenna, or connect an external GPS antenna (option
GPA) to the HSA and make sure the head of the external GPS antenna is in
an open space.
Turn on GPS [Shift], [System], {More 1 of 2}, {GPS}, {GPS, (On)}
A icon will appear at the top of the display after successful lock of GPS
satellites
Turn on GPS information on the display {GPS Info, (On)}

Note: The N934xC must have an unobstructed view of the sky in order to lock onto GPS satellites.
The HSA has a built-in GPS receiver and antenna (Option GPS). In addition to the internal
antenna, the HSA also supports the external GPS antenna (Option GPA), providing
convenience in the eld. You can save measurement results with GPS location data
(latitude, longitude, and altitude).
In this demonstration, we will show how to use the N934xC HSA`s GPS feature.

Task planner is a unique tool provided with N934xC HSA as an optional feature. It’s easy
to sequentially execute many pre-dened measurements, log results, and generate
reports automatically.
The measurement modules which task plan supports include: SA, ACP, CHP, and OBW.
One task planner le (*.tpf) can execute up to 20 test tasks.
In this demonstration, we will compile a task planner le (w_cdma.tpf) and run it. Before
compiling it, you must install N934xC HSA PC software and the Keysight Technologies,
Inc. I/O library on your PC (download available at www.keysight.com/nd/hsapc).

Option SIM provides a spectrogram that provides a three-dimensional
display of the spectrum with power over frequency and time. This
feature helps nd intermittent interference signals, as well as locate
and identify unwanted signals that cause dropped calls and poor
quality service in communications systems. The X-axis represents
frequency as in a normal spectrum display, but amplitude is
represented by color: red for a strong signal and blue for noise oor.
The Y-axis represents time, with the trace from the newest sweep
displayed at the bottom of the screen. Earlier traces move up towards
the top of the screen with each new sweep. Two coupled markers allow
you to place a marker on any trace in the spectrogram and view the
normal spectrum for the time of that sweep. The time interval between
sweeps can be adjusted, and up to 1,500 traces can be displayed and
saved.
In this demonstration, the N9311X-500 whip antenna is used to receive
over the air GSM uplink signal. For interference hunting application, a
directional antenna like the N9311X-504 is recommended.

In order to keep a communication system working reliably long term, you need to monitor
the spectrum routinely. Regular spectrum monitoring is usually accomplished automati-
cally by using remote control software to drive the spectrum analyzer. You can remotely
control the HSA using SCPI commands over LAN and USB, or use the HSA PC software
to monitor spectral changes. There are two modes that are used to set up the HSAs’ LAN
IP address: static and DHCP.
In this demonstration, we will show how to set HSA’s IP address.

The N934xC HSAs each have a total of six markers that can be used in normal or delta
mode. In addition to the marker table and peak search, each N934xC HSA also has a
peak table feature which automatically searches 10 max or min peak signals simultane-
ously and is updated after each sweep.
In this demonstration, we will use peak table to nd the absolute values of FM signal
sidebands.
Note: To prevent data corruption when saving the table to a USB memory device, set
the le directory to USB then reset to INT before removing the device.

The N934xC HSAs provide powerful marker functions. In addition to normal and delta
marker modes, the instrument marker system provides noise markers, frequency counter
markers, AM/FM tune and listen, and band power measurement. For the AM/FM tune
and listen feature, the AM/FM demodulated audio can be heard with the internal
speaker or the provided headphone. Speaker volume and delay time can be adjusted to
meet your specic needs.
In this demonstration, we will perform an AM/FM tune and listen measurement using an
external AM/FM antenna.

The N934xC HSA offers two different limit lines. Limit lines/limit masks and associ-
ated margins allow you to quickly and easily identify signals that do not meet specied
requirements.
In this demonstration, we will create a limit line and perform a pass/fail test.
