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.
1.1 Adjust the display brightness
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
Switch the screen brightness state back to automatic {Brightness (Auto)}
Cover the light sensor with your nger and watch as the display bright-
ness adjusts automatically
1.2 Back-lit key demo
Instructions for HSA Keystrokes for HSA
Turn on key backlight [Shift], [System], {Keypad Setting}, {Backlight Brightness}, {Auto}
Adjust backlight ash time to 5, 10, 15, 30 seconds, or “always on” {Backlight off}, {15 s}

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.
Instructions for the source Keystrokes for the source
Set 2 GHz center frequency, amplitude -10 dBm, CW signal [Preset], [FREQ], [2], {GHz}, [AMPTD], [-10], {dBm}, [RF On]
Instructions for HSA Keystrokes for HSA
Tune the center frequency to 2 GHz [Freq], [2], {GHz}
Adjust span so signal lls the screen [Span], [10], {MHz}
Set reference level to
-10 dBm so that the signal peak is at the top of graticule line (Figure 2)
[Amptd], {Ref Level}, [-10], {dBm}

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)}
Location information from GPS displays on the right of icon (Figure 3)
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.
