OPERATING INSTRUCTIONS

Intended Use

The Model 2340/2350 Amplifier is a two-channel, high voltage amplifier capable of both sourcing and sinking current for a variety of loads including resistive and reactive loads. It was specifically designed for applications that require the output voltage range of standard signal or function generators to be extended beyond their typical range to ±200V. The 2340/2350 amplifier is compatible with virtually all types of signal and function generators.

Monitor Outputs

Each main output is accompanied by a monitor output. The monitor output is designed to provide an accurate, low-voltage representation of the amplifier output at a scale of 100:1 when feeding into a 1MΩ input and of 200:1 when feeding into a 50Ω input. The basic 2340/2350 amplifier gain is set to +50 with no inversion.

Voltage & Current Limitations
It should be noted that the maximum input of the 2340/2350 amplifier should not exceed ±4V. This would cause the output signal to exceed ±200V causing the output signal to clip resulting in severe distortion. The amplifier is protected in all operating modes with current limiting in either positive or negative directions. The maximum operating current of each output is rated for 40mA.

Frequency Characteristics
The 2340/2350 is capable of amplifying small signals from DC to 2MHz. The bandwidth of any amplifier decreases as the output amplitude approaches the instrument’s maximum limits. There are several figures in the specification section of this manual that illustrate the frequency response, amplitude, output power and distortion characteristics of the 2340/2350. Included in these figures is a distortion versus frequency curve where the instrument’s output is set to 75% of maximum amplitude (300Vp-p). Notice the steep frequency roll off when the amplifier’s signal approaches its slew limitations. The 2340/2350 has a full power bandwidth that exceeds 200kHz.

Protection Ciruits

The 2340/2350 amplifier has a LINE POWER switch and a power indicator on the front panel. The power indicator will illuminate when the high voltage DC supply is connected to the output power amplifiers. Under normal operation, the power indicator will illuminate approximately 2 seconds after the LINE POWER switch is turned on. However, if a high voltage DC fault occurs, the power supply monitor will protect the power amplifiers by disconnecting the high voltage supply from the output amplifiers. This will cause the power indicator to shut off. The fault will latch and the power indicator will remain off until the AC power is cycled to reset the fault. The 2340/2350 also has a current limit function to protect the outputs against short circuits etc.

Connections
The amplifier’s inputs require standard BNC connections and have an impedance of 50Ω. This makes it compatible with all TEGAM-Pragmatic or other conventional signal generators. The output is specified at less than .2Ω. Two output cables are supplied with the 2340/2350. These are special cables, which have high-voltage BNC connectors on one end and standard BNC connectors on the other. The cables are designed for use with the high voltage output connectors on the front panel. There is a binding post available on the instrument’s front panel to be used as a direct connection to the instrument’s chassis. The monitor outputs may be connected using any standard type BNC to BNC cables to an oscilloscope, A/D card or other compatible monitoring device.

SERVICE INFORMATION

Inspection and Cleaning

The cooling fan is designed for continuous operation. Periodically check the fan to make sure that airflow is not impeded and that there is adequate ventilation to keep the instrument cool.
TEGAM recommends that the 2340/2350 be calibrated and routine functional checks be performed on a regular basis. The recommended interval is every twelve months. The actual interval is dependent upon the application and is determined by your company’s Quality Assurance policy.

CAUTION
Servicing and calibration must be done by qualified service personnel.

WARNING
When disassembling the Amplifier for calibration, turn power OFF and disconnect the power cord from the AC power source.

Calibration

Alignment Procedure

Preparation Required Equipment:

Function Generator
Fluke 8842A – 51/2 digit Digital Multimeter or equivalent 50Ω BNC Splitter

Remove the Amplifier’s front and back bezels by pulling out on the left or right side to release the plastic from the metal sub panel. Rotate the released edge away from the panel 1 to 2 inches and move the bezel toward unreleased side and remove.
Remove the 2 top and 2 bottom sheet metal screws from the 4 corners of the rear panel.
Remove the 2 sheet metal screws from the 2 top corners of the front panel.
Carefully slide the rear panel out far enough so that the top cover can be grasped. Then slide the top cover back 3 to 4 inches so the offset and gain access hole adjustments at the front on the unit are visible. Refer to Figure 1.
Before connecting the power cord to the Amplifier verify that all wiring is routed away from metal surfaces.

TEGAM-2340-High-Voltage-Amplifier-fig-3

Turn the 2340/2350 power ON and allow for the 2340/2350 to warm up for at least 15 minutes.
Verify that no instruments are connected to the Channel 1 or Channel 2 (2350 only) inputs.
Connect the DVM to Channel 1 OUTPUT and adjust the Channel 1 OFFSET potentiometer to 0.0 ± 5 mVDC.
Apply a 4 Vpp (1.414 Vrms), 10 kHz, Sine wave to Channel 1 INPUT (with a BNC T-connector). Measure and [RECORD] the AC voltage with the DVM connected to the other end of the T-connector. Refer to Figure 2.
Multiply the recorded voltage from Step 9 by 50 and [RECORD].
Connect the DVM to Channel 1 OUTPUT and adjust Channel 1 GAIN potentiometer for the recorded voltage from Step 10 ± 0.2 Vrms.
If a dual channel amplifier is being calibrated, repeat Steps 7 through 11 for Channel 2.
Turn power OFF and disconnect the power cord from the AC power source.
Assemble the unit in the reverse order of disassembly.

Preparation for Calibration or Repair Service

Once you have verified that the cause of the malfunction cannot be solved in the field and the need for repair and calibration service arises, contact TEGAM customer service to obtain an RMA (Returned Material Authorization) number. You can contact TEGAM customer service via the TEGAM website (www.tegam.com) or by calling 440-466-6100 (All Locations) or 800-666-1010 (United States Only).
The RMA number is unique to your instrument and will help us identify your instrument and to address the particular service request by you which is assigned to that RMA number.
Of even greater importance, a detailed written description of the problem should be attached to the instrument. Many times repair turnaround is unnecessarily delayed due to a lack of repair instructions or a detailed description of the problem.
This description should include information such as measurement range and other instrument settings at the time of the malfunction, type of components being tested, frequency of the symptoms (intermittent or continuous), conditions that may cause the symptoms, changes to the test setup or operating environment that may affect the instrument, etc. Any detailed information provided to our technicians will assist them in identifying and correcting the problem in the quickest possible manner. Use a copy of the Repair and Calibration Service form provided on the next page.
Once this information is prepared and sent with the instrument to our service department, we will do our part to make sure that you receive the best possible customer service and turnaround time possible.

Expedite Repair & Calibration Form
