INTRODUCTION

The AVH-HV1-C is a high performance instrument capable of generating up to 100

Volts into 50Ω loads at repetition rates up to 100 kHz. The output pulse width is 1 ns or less (800 ps or less for units with the -T1 option), measured at the 20% rise time point

(the FWHM pulse width is less).

Instruments with the "-P" model suffix can generate up to +100V, whereas instruments with the "-N" model suffix can generate up to -100V. Instruments with the "-PN" suffix can generate both polarities.

The output is designed to drive 50Ω loads. (A 50Ω load is required for proper operation.) The output is AC-coupled.

This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel.

REGULATORY NOTES

FCC PART 18

This device complies with part 18 of the FCC rules for non-consumer industrial, scientific and medical (ISM) equipment.

This instrument is enclosed in a rugged metal chassis and uses a filtered power entry module (where applicable). The main output signal is provided on a shielded connector that is intended to be used with shielded coaxial cabling and a shielded load. Under these conditions, the interference potential of this instrument is low.

If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech ([email protected]) for advice if you are unsure of the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure.

If any of the connectors on the instrument are unused, they should be covered with shielded metal “dust caps” to reduce the interference potential.

This instrument does not normally require regular maintenance to minimize interference potential. However, if loose hardware or connectors are noted, they should be tightened. Contact Avtech ([email protected]) if you require assistance.

1) POWER Switch. This is the main power switch. When turning the instrument on, there may be a delay of several seconds before the instrument appears to respond.

2) OVERLOAD Indicator. When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an internal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low impedance), the protective circuit will disable the output of the instrument and turn the indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after which the instrument will attempt to re-enable the output (i.e. light green) for about

1 second. If the overload condition persists, the output will be disabled again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation.

This overload indicator may flash yellow briefly at start-up. This is not a cause for concern.

3) PRF Range Switch. This switch sets the pulse repetition frequency (PRF) range of the internal oscillator. The marked value of each position is the upper limit of the

10:1 range, approximately. The vernier dial directly below the switch varies the PRF within the set range.

If this switched is set to the “EXT” position, the instrument is triggered by a signal applied to the TRIG connector, rather than by the internal oscillator.

4) TRIG Connector. When the PRF Range Switch is set to “EXT”, the instrument is triggered by a TTL pulse applied to this connector. The pulse must be at least 50 ns wide.

When the PRF Range Switch is set to one of the four internal oscillator ranges, this connector is an output, which supplies a 3V, >50 ns wide pulse for each trigger

16 event. This output may be used to trigger oscilloscopes or other equipment.

5) Delay Controls. When the PRF Range Switch is set to one of the four internal oscillator ranges, the main output is advanced or delayed relative to the TRIG output pulse (item 3). The delay is variable up to 200 ns, approximately, using the

DELAY and DELAY FINE dials.

6) Amplitude Control. This dial controls the amplitude.

7) Polarity Switch. (Present on -PN units only.) This switch controls the output polarity

(positive or negative).

8) OUT Connector. This SMA connector provides the main output. This output

requires a 50Ω load to function properly.

2. AC FUSE DRAWER. The two fuses that protect the AC input are located in this drawer. Please see the “FUSES” section of this manual for more information.

3. DC FUSES. These two fuses protect the internal DC power supplies. Please see the

“FUSES” sections of this manual for more information.

4. OS INPUT CONNECTOR. (Present on units with -OS option only.) A DC offset in the range of ±50V (250 mA max) may be applied to this solder terminal. The DC offset will appear on the output. When this feature is not used, the OS input should be connected to ground (using the adjacent GND connector). This is especially important when driving loads containing a diode.

5. GND CONNECTOR. (Present on units with -OS option only.) This solder terminal is connected to ground. It may be used to ground the OS input connector.

GENERAL INFORMATION

BASIC TEST ARRANGEMENT

The AVH-HV1-C should be tested with a sampling oscilloscope with a bandwidth of at least 12 GHz to properly observe the high-speed waveform. A typical test arrangement is shown below:

The attenuators are required to prevent damage to the sampling oscilloscope. A 40 dB attenuator with sufficient bandwidth should be used on the main output.

BASIC PULSE CONTROL

This instrument can be triggered by its own internal clock or by an external TTL trigger signal. When triggered internally, two mainframe output channels respond to the trigger: OUT and SYNC.

 OUT. This is the main output.

 SYNC. The SYNC pulse is a 3V, > 50 ns reference pulse used to trigger oscilloscopes or other measurement systems.

These pulses are illustrated below:

The AVH-HV1-C can also be triggered by a TTL-level pulse applied to the TRIG input.

AMPLITUDE INTERACTION

Some properties of the output pulse may change as a function of the amplitude setting.

For some demanding applications, it may be desirable to use a combination of external attenuators and the amplitude pot to achieve the desired output amplitude.

19

OPERATION AT LOW AMPLITUDES

This instrument will generate the best waveforms when operated near maximum amplitude. If amplitudes less than 1/3 of the full-scale value are desired, better results will be obtained if the pulse generator is operated at a higher amplitude, and an attenuator is connected to the output.

For attenuator input voltages exceeding 50 Volts, Avtech suggest the Midwest

Microwave ATT-0527-XX-SMA-07 family of fixed 12 GHz, 20 Watt attenuators. A 20 dB attenuator of this type is included with the -AK2 option.

At lower voltages, Avtech recommends the BW-SxxW2+ series of 18 GHz coaxial attenuators from Mini-Circuits, http://www.minicircuits.com/ . (The “xx” in the part number is replaced with the numeric attenuation value in dB). 10 and 20 dB attenuators of this type are included with the -AK2 option.

OSCILLOSCOPE SELECTION AND BANDWIDTH ISSUES

To observe a signal with a rise time of t exceed 1/t

R

. For the AVH-HV1-C-T1 typical rise times (20%-80%) may be as fast as

~180 ps, so 1/t

R

R

, the bandwidth of the oscilloscope must

= 1 / 180 ps = 6 GHz. For best results, the bandwidth of the oscilloscope (and any attenuators and cables used in the measurement system) should exceed 12 GHz.

20

Most oscilloscopes with suitable bandwidth are "sampling" oscilloscopes, which are more specialized in nature than slower conventional "real-time" oscilloscopes. Most sampling oscilloscopes have a very limited input voltage range (±1V, for example). It is essential in these cases to use high-bandwidth attenuators on the input of the oscilloscope, to avoid over-driving or damaging the oscilloscope.

If a high-bandwidth sampling oscilloscope is not available, a slower real-time oscilloscope can be used, but the rising and falling edges will not be accurately displayed. Significant overshoot and ringing will be observed as a result of the oscilloscope's limited bandwidth.

(Contrary to some user's expectations, low-bandwidth oscilloscopes do not "round off" the signal like a classic low-pass filter.) These are measurement artifacts, and are not normally present on the actual output.

21

MINIMIZING WAVEFORM DISTORTIONS

USE 50

Connect the load to the pulse generator with 50Ω transmission lines (e.g. RG-58 or

RG-174 cable).

This instrument requires a 50Ω load for proper operation. It will not properly drive a high-impedance load. The output stage will be damaged if it is operated into an open circuit (or any other high impedance). Failures due to improper output loading are not covered by the warranty.

USE LOW-INDUCTANCE LOADS

Lenz’s Law predicts that for an inductive voltage spike will be generated when the current through an inductance changes. Specifically, V the inductance, I

LOAD

SPIKE

= L × dI

LOAD

/dt, where L is

is the load current change, and t is time. For this reason, it is important to keep any parasitic in the load low. This means keeping wiring short, and using low inductance components. In particular, wire-wound resistors should be avoided.

PREVENTING DAMAGE

The AVH-HV1-C may fail if triggered at a PRF greater than 100 kHz.

This unit is designed to operate into a load impedance of 50 Ohms and the output stage will be damaged if it is operated into an open circuit (or any other high impedance). Failures due to improper output loading are not covered by the warranty.

The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. For this reason the prime power to the instrument should be turned off when the instrument is not in use.

22

MECHANICAL INFORMATION

TOP COVER REMOVAL

If necessary, the interior of the instrument may be accessed by removing the four

Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off).

Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument. This will allow any internal stored charge to discharge.

There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech ([email protected]) to arrange for the instrument to be returned to the factory for repair. Service is to be performed solely by qualified service personnel.

Caution: High voltages are present inside the instrument during normal operation.

Do not operate the instrument with the cover removed.

RACK MOUNTING

A rack mounting kit is available. The -R5 rack mount kit may be installed after first removing the one Phillips screw on the side panel adjacent to the front handle.

ELECTROMAGNETIC INTERFERENCE

To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused outputs should be terminated with shielded coaxial terminators or with shielded coaxial dust caps, to prevent unintentional electromagnetic radiation. All cords and cables should be less than 3m in length.

MAINTENANCE

REGULAR MAINTENANCE

This instrument does not require any regular maintenance.

On occasion, one or more of the four rear-panel fuses may require replacement. All fuses can be accessed from the rear panel. See the “FUSES” section for details.

CLEANING

If desired, the interior of the instrument may be cleaned using compressed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommended.
