Introduction to Instrument
Front Panel at a Glance
The BNC connectors, both the shell and center pin, on the front panel of the instrument are isolated up
to ±42 Vpk from chassis. The shells of these BNC connectors are connected to each other, and internal
circuitry will attempt to keep the isolated voltage to within ±42 Vpk to chassis. Exceeding the isolation
voltage beyond ±42 Vpk from chassis may destroy the instrument and cause a hazard that could result
in personal injury or death.

The external 10 MHz reference input BNC connector, both the shell and center pin, on the rear panel of
the instrument is isolated up to ±42 Vpk from chassis. The shell of this BNC connector is isolated from
the rest of the instrument. Internal circuitry will attempt to keep the isolated voltage to within ±42
Vpk to chassis. Attempts to float this input beyond ±42 Vpk from chassis may destroy the instrument
and cause a hazard that could result in personal injury or death.
The external modulation input BNC connector, both the shell and center pin, on the rear panel of the
instrument is isolated up to ±42 Vpk from chassis. The shell of this BNC connector is connected to the

Quick Start
Prepare Instrument for Use
Verify that you received the following items. If anything is missing, please contact your nearest Agilent sales office or
Agilent authorized reseller.
l Power cord (for country of destination)
l Certificate of Calibration
l Agilent Trueform Series Product Reference CD (product software, programming examples, and
manuals)
l Agilent IO Libraries Suite CD
l USB 2.0 cable
Note: All product documentation is on the Agilent Trueform Series Product Reference CD. For the
latest firmware and documentation, see www.agilent.com/find/trueformhelp. The latest version of
the documentation is also available for mobile devices at www.agilent.com/find/trueformmobile.
You may also scan the following QR code with your smart phone or tablet to go to the mobile
documentation.
The instrument may be used with mains power of either 100-240 V, 50/60 Hz or 100-120 V, 400 Hz. The maximum
power usage is 150 VA. Ensure that you are using the correctly rated mains cord based on the instrument’s rating and
your country's electrical codes. Connect the power cord and LAN, GPIB, or USB cable as desired. Turn the instrument
on by pressing the power switch in the lower left corner of front panel. The instrument runs a power-on self test and
then displays a message about how to obtain help, along with the current IP address. It also displays the GPIB address if
the GPIB option is installed and enabled.
PowerSwitch:
The instrument's default function is a 1 kHz, 100 mVpp sine wave (into a 50 Ω termination). At power-on, the channel
output connectors are disabled. To enable output on a channel connector, press the key above the channel connector
and then press the Output Off / On softkey.
If the instrument does not turn on, verify that the power cord is firmly connected. Also make sure that the instrument
is connected to an energized power source. If the LED below the power switch is off, there is no AC power connected. If
the LED is amber, the instrument is in standby mode with AC power connected, and if it is green, the instrument is on.
24 Agilent Trueform Series Operating and Service Guide
Quick Start
If the power-on self test fails, the display shows ERR in the upper right corner. It also prominently displays "Check for
error messages in the error queue."
See SCPI Error Messages for information on error codes. See Service and Repair - Introduction for instructions on
returning the instrument for service.
To turn off the instrument, hold the power switch down for about 500 ms. This prevents you from turning the
instrument off by accidentally brushing the power switch.
Adjust the Carrying Handle
Grasp the sides of the handle, pull outward, and rotate the handle.

26 Agilent Trueform Series Operating and Service Guide
Set Output Amplitude
The instrument's default function is a 1 kHz, 100 mVpp sine wave (into a 50 Ω termination).
The following steps change the amplitude to 50 mVpp.
1. Press [Units] > Amp/Offs or High/Low to make sure that you are in Amp/Offs.
The displayed amplitude is either the power-on value or the amplitude previously selected. When you change
functions, the same amplitude is used if it is valid for the new function. To choose whether you want to specify
voltage as amplitude and offset or high and low values, press [Units] and then the second softkey. In this case,
we will highlight Amp/Offs.
Quick Start
2. Enter the magnitude of the desired amplitude.
Press [Parameters] > Amplitude. Using the numeric keypad, enter the number 50.
3. Select the desired units.
Press the softkey that corresponds to the desired units. When you select the units, the instrument outputs the
waveform with the displayed amplitude (if the output is enabled). For this example, press mVpp.
You can also enter the desired value using the knob and arrows. If you do so, you do not need to use a units
softkey. You can easily convert unit types. Simply press [Units] > Ampl As and select the desired units.
Agilent Trueform Series Operating and Service Guide 27
Quick Start
Set DC Offset Voltage
At power-on, the DC offset is 0 V. The following steps change the offset to –1.5 VDC.
1. Press [Parameters] > Offset.
The displayed offset voltage is either the power-on value or the offset previously selected. When you change
functions, the same offset is used if the present value is valid for the new function.
2. Enter the desired offset.
In this case we will use the numeric keypad to enter –1.5.
3. Select the desired units.
Press the softkey for the desired units. When you select the units, the instrument outputs the waveform with the
displayed offset (if the output is enabled). For this example, press V. The voltage will be set as shown below.
You can also enter the desired value using the knob and arrows.
