HMC-T2100 Synthesized Signal Generator User Manual
3. General Overview of Instrument Capabilities
The HMC-T2100 is a single channel frequency synthesizer. The block diagram for this unit is shown in
figure 1. This unit provides one RF output channel with programmable output frequency and output power.
The output frequency range is programmable from 10 MHz to 20 GHz in 10 KHz increments. The synthesizer
provides an internal 10 MHz reference source which can be overridden by an external source. An AC wall
type power supply is provided to generate the required DC power for the unit. The detailed performance
specifications for the synthesizer are listed in the datasheet on the Hittite website.
The user may control the frequency, power, and RF Standby functions from either the Front Panel or the
peripheral interfaces which include a USB, Ethernet[1], and GPIB interface [1]. The RF Standby function will
apply the maximum attenuation to the RF output.

4. Installation of Equipment and Safety
The guidelines shown below must be followed for proper installation of the SG equipment:
• The SG equipment was designed for LABORATORY USE ONLY and is not protected against
moisture.
• Utilize appropriate ESD handling procedures and precautionary measures when installing this
equipment.
• The SG unit is intended for placement on a laboratory workbench.
• During install make certain there are no obstructions that would impede air flow to the venting of
the unit on the sides of the enclosure, or the fans located on the rear panel.
• Ensure that all external components and RF/microwave coaxial cables are in proper condition.
• A grounded, three pin AC power receptacle should be used to connect power to the AC wall
power supply. It is recommended that the ON/OFF power switch on the front panel be used to
interrupt power to the unit. Interrupting power by pulling out the AC cord may result in injury or unit
damage.
[1] Ethernet & GPIB Interface are not operational until June 2009.

are ReMap Hardware, Open, Close, Refresh, and Disable Power Checks. The top right pull-down menu
will provide a list of connected T2100 synthesizers after the application has been opened. Some of the
features below may be accessed through the button below the hardware pull-down menu. The function
of this button changes depending on the state of the software.
5.5.2 ReMap Hardware
If synthesizer’s are added to the computer after the application has been opened, the ReMap Hardware
function may be used to force the computer to go and check for any new synthesizer units.
5.5.2.1 Open
The Open function is used to establish a connection to a specified synthesizer. A synthesizer is selected
with the upper right hand pull-down menu.
5.5.2.2 Close
The Close function is used to disconnect the currently selected synthesizer. A new synthesizer may then
be selected with the upper right hand pull-down menu, and the Open function.
5.5.2.3 Refresh
Once a synthesizer has been selected with the Open command, the Refresh function may be used
to read the current status of the synthesizer. If the GUI checkbox for Remote and Local Lockout has
not been checked, the Refresh function will read the current status of the unit as commanded via the
synthesizer’s front panel.
5.5.2.4 Disable Power Checks
Within the menu this function may be selected to disable software power level checking.
5.5.3 Synthesizer Selection Menu
This is a pull-down menu at the top right hand side of the GUI. All synthesizers which have been
detected by the software are displayed in this menu. If synthesizers are added to the computer after the
application has been started, use the ReMap Hardware function to force the software to check for other
synthesizers.
5.5.4 Remote and Local Lockout
The Remote and Local Lockout feature is enabled by a checkbox available within the GUI. When the
checkbox is selected, computer controlled operation via the USB is enabled. Front panel control of the
unit is disabled. If this checkbox is not selected, the software application will not change any settings
in the synthesizer. However in this state, if the Refresh button is depressed, the current Frequency and
Power fields will be updated with the current settings within the synthesizer.
5.5.5 Frequency Field
When the Remote and Local Lockout checkbox is selected, the Frequency of the synthesizer may be con-
trolled with the text-box. The desired frequency can be either typed into the provided text-box, or either
the up and down arrows on the keyboard, or the GUI field may be used to increment or decrement the
frequency by the amount indicated in the Step box. After a new frequency has been entered, the appli-
cation attempts to set the synthesizer to the commanded frequency. If for any reason (Example: outside
the calibration range) the unit does not go to the commanded frequency, the field will be highlighted in
yellow.
