General information
The PNA 4500 is a vector network analyser with a built-in Windows PC. It can be operated either
stationary with the 230 V AC power supply unit or mobile with the battery compartment.
The PNA 4500 can be operated either directly or remotely. No special software is required for remote
operation. Operation is browser-based. The browser-based terminal is connected via the back-side
LAN port. If a mobile WLAN router is connected to this port, the PNA 4500 can also be remotecontrolled via a web browser on a smartphone, tablet etc.
The screen of the PNA 4500 is a touch-sensitive touch screen monitor. Operation is carried out via
dynamic buttons on the screen, via direct selection buttons below the screen, via a 10-keys keyboard
as well as with the rotary / push button control to the right of the screen. Alternatively, a keyboard, a
mouse and printer can be connected via the back USB ports.
Note: Some of the functions described are not included in the standard scope of the Network
Analyser and require optional accessories or optional software.

Warnings:
In order to achieve precise measurement results, the PNA 4500 is equipped with high-quality,
broadband measurement detectors. Please note that these sensitive detectors can be damaged or
destroyed if they are charged with excessive energy.
Avoid static discharges via these measuring connections, which can occur when connecting test
specimens to the RF IN or RF OUT connector. If necessary, ensure that static charges are dissipated,
e.g. by attaching a grounded ESD antistatic wristband.
The detectors measure existing signals in a broadband spectrum (100 kHz - 3 GHz), even if the display
in the measurement diagram is reduced to the desired range. As a result, large signals exceeding
certain maximum values can lead to falsified measurement results and possibly to damage of the
measurement detectors.
ATTENTION: In order to measure the transmitter output power of radio devices, these must only be
connected to the external power detector.
The maximum levels of the measuring connections are:
RF OUT (reflection measurement):
Max. return power: + 20 dBm (= 100mW), 16V DC
RF IN (input level measurement):
Max. input power:
- At 0 dB attenuation: +20 dBm (= 100 mW), 0 V DC
- At> 7 dB attenuation: +27 dBm (= 500 mW), 0 V DC
External detector (power measurement):
Max. transmission power: depending on the measuring head (typ. +20 to +43 dBm (100 mW to 20
Watt). See type plate.
Higher power measurements are possible with pre-connected attenuators.

Operation of the PNA 4500:
1. Power supply :
The power supply for the PNA 4500 is either via the battery compartment or via the supplied 230 V
AC charger. Please note that the use of a different charger will void the warranty and may cause
serious consequential damages to the product.
The main switch on the back of the battery compartment has to be set to "1" to:
- use the PNA 4500 in mains operation and simultaneously charge the battery.
- charge the battery pack in the compartment when it is not in the PNA 4500.
The status LED of the battery pack indicates the current charging status:
- red flashing = battery is charging
- red = fault
- green = battery is fully charged
The battery compartment is accessible
on the back of the device and can be
replaced from the outside. To do this,
the three knurled screws must be
loosened, then the compartment can be
pulled out.
When inserting the battery
compartment, make sure that the
contact strip is positioned correctly
before tightening the three knurled
screws.
The battery compartment contains the
battery block (4.4 Ah, NiMh) as well as
the charging electronics. Thus, an
optional additional battery
compartment can be loaded separately
from the PNA 4500. The 230 V AC
charger is to be used for charging.

2. Switch on the PNA 4500
Press the on/off switch at the bottom left until the status LED that is placed over it starts to flash.
The PC starts the Windows operating system and configures the PNA 4500 software.
Note: If the backside main switch is set to "0", the power is supplied via the battery compartment.
For operation via the 230 V AC charger, turn the main switch to "1".

General information on the measurement of GPS antennas:
GPS antennas are checked using a GPS receiver located in the PNA 4500. The GPS antenna to be
measured is connected to the backside SMA socket.
Depending on the GPS system the measurement process can take a different length of time and
depends on many factors. An important factor is the last saved position. If the GPS antenna is
measured near the last saved position, the measurement result is available at short notice. If the PNA
4500 has changed its location significantly since the last GPS measurement, the new time and
position data of the GPS satellites may have to be read again. The new reading of these data, also
called Almanach, corresponds to a typical "GPS cold start" and can take up to 12.5 minutes. The
measurement can then be started.
The GPS receiver can receive up to 12 GPS satellites simultaneously. These 12 satellites are displayed
in tabular form with elevation and azimuth angles as well as signal-noise ratio (SNR = signal/noise
ratio). The higher this SNR value, the greater the distance between the useful signal and the noise
signal. A well-functioning antenna is thus characterized by GPS values with high SNR values.
The values shown in yellow represent the relevant results.
SAT = Displays the number of usable satellites.
SNR HI = Displays the highest SNR value of all usable satellites.
SNR / SAT = Display the SNR mean value of all usable satellites
SNR / 12 = Display the SNR mean value of all 12 satellites (also not usable ones)
The measured values are displayed in three lines:
Line 1 NOW Values of the current measurement
Line 2 MAX Maximum values during the set measuring period
Line 3 AVG Average values of all measurements during the set measuring period
In addition, the GPS UTC time (Universal Time Coordinated) and the length and latitude of the GPS
measurement are displayed, provided that at least three satellites have analyzable usable signals.

Setup of keyboard language
The PNA 4500 can be operated with different input devices, which are connected via the USB ports,
depending on the input possibilities the user prefers. The Windows functionality supports different
keyboard languages, so that you can use QWERTY or QWERTY keyboards. The on-screen keyboard
can also be changed accordingly. The keyboard language is set as follows:
1. Open the control panel and click on "CHANGE KEYBOARDS OR OTHER INPUT METHODS".

2. In the upper line, select the tab "KEYBOARD
AND LANGUAGES" and click the
"CHANGE KEYBOARDS" button.
3. Select “ADD“.
4. Use the "Arrow down" key to scroll down until
the desired language is reached. Then open the
entry and place the check mark accordingly. Then
confirm with "ok".
5. Now the desired language can be
