This manual is common to Models 9100A, 9200A and Model 9400. All instruments are built on the same platform and share specifications and features except the 9100A is a single channel version, the 9200 has two channels and 9400 has four channels.

Unpacking and handling of the generator requires normal precautions and procedures applicable to handling of sensitive electronic equipment. The contents of all shipping containers should be checked for included accessories and certified against the packing slip to determine that the shipment is complete.

Extreme safety precautions should be observed before using this product. Although some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous conditions may be present.

This product is intended for use by qualified persons who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury. The following sections contain information and cautions that must be observed to keep the 9400 operating in a correct and safe environment.

9100A/9200A/9400

CAUTION

For maximum safety, do not touch the product, test cables, or any other instrument parts while power is applied to the circuit under test. ALWAYS remove power from the entire test system before connecting cables or jumpers. Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always keep your hands dry while handling the instrument.

Operating Environment

The 9400 is intended for indoor use and should be operated in a clean, dry environment with an ambient temperature within the range of 0 °C to 40 °C.

1-2 Installation

9100A/9200A/9400

Power Requirements

The 9400 operates from one of the following nominal sources: 100V, 115V, or 230V ac. Voltage selection is done using the rearpanel power line selector switch. The instrument operates over the power mains frequency range of 47 to 63 Hz. Always verify that the operating power mains voltage is the same as that specified on the rear panel voltage selector switch.

The 9400 is supplied with the correct power line setting. If this setting needs to be change, use a flat-head screwdriver to set the Line Selector switch on the rear panel to the required position.

The instrument is not intended for operation from two phases of a multi-phase ac system or across the legs of a single-phase, three-wire ac power system. Crest factor (ratio of peak voltage to rms) should be typically within the range of 1.3 to 1.6 at 10% of the nominal rms mains voltage.

WARNING

DO not connect the line cord to the 9400 before you verify the correct power line setting. Failure to switch the instrument to match the operating line voltage will damage the instrument and may void the warranty.

Grounding Requirements

Calibration

To conform to the applicable safety and EMC requirements, ensure that the Model 9400 is “earth” grounded. Always connect the power using the supplied power cord with the earth pin connected securely to the wall mount socket.

Signals connected to the amplifier inputs and to the amplifier outputs are grounded through the outer shell of the BNC connectors. Never attempt to float the signal from case ground as it may damage the source equipment.

The recommended calibration interval is three years. Calibration should be performed by qualified personnel only.

Preparation for Use

Bench Installation

Rack Mounting

Preparation for use includes removing the instrument from the box, the bag and installing the 9400 either on the bench or in a 19” rack. Chapter 2 of the manual contains operating instructions. Make sure you read and understand the instructions in Chapter 2 before turning on the device.

The 9400 dissipates large amount of power. No special cooling is required. However, the instrument should not be operated where the ambient temperature exceeds 40 °C, when the relative humidity exceeds 80% or condensation appears anywhere on the instrument. Avoid operating the instrument close to strong magnetic fields, which may be found near high power equipment such as motors, pumps, solenoids, or high power cables. Always leave 4 cm (about 1.5 inches) of ventilation space on all sides of the instrument.

The 9400 can be rack mounted inside a standard 19” rack. It can be mounted using one of two configurations: 1) single, or 2) side-byside. Tabor offers rack-mounting ears for both options. Consult the factory for the appropriate part number.

Using the single rack mounting option, the 9400 is supplied with a blank panel that covers the empty side. The case can be mounted either on the left or the right of the rack with the blank panel covering the empty space.

Side-by-side option is available only with other Tabor products. In this case, the two boxes are latched in the middle and side ears connect the assembly to the rack. Figure 1-1 shows how the 9400 can be mounted next to a dual-channel arb – Model 2572.

Use care when rack mounting to locate the instrument away from sources of excessive heat or magnetic fields. Always leave 4 cm (1.5 inches) of ventilation space on top and bottom sides of the power amplifier.

Introduction and Operating Instructions

What’s in This Chapter

Introduction

This chapter contains general and functional description of the Models 9100A, 9200A and 9400 – high voltage, wideband amplifier series. It also describes the front and rear panel connectors, operational modes and all features available with the instruments.

Description

Models 9100A, 9200A and 9400 were designed as a general purpose series, wide band and high voltage amplifier however, with specific applications in mind. It has up to four channels built in a small case size to save space and cost but without compromising bandwidth and signal integrity. The Model 9100A is shown in Figure 2-1, model 9200A is shown in Figure 2-2 and model 9400 in Figure 2-3. All instruments are built on the same platform and share specifications and features except the 9100A is a single channel version, the 9200A is a dual channel version and the 9400 has four channels.

NOTE

The 9400 is intended to operate as an amplifying buffer for signals such as available from waveform, function, or pulse generators. Most of these generators can produce signals that are limited to 20 Vp-p into high impedance, so the 9400 can be used to convert these voltages to levels as high as 400 Vp-p.

The amplifier case was designed to stack on top or below other Tabor products. It measures 2U high and ½ rack size. It also can be mounted next to a Tabor generator in a standard 19” rack, as shown in Figure 2-4. The arbitrary waveform and amplifier combination is a perfect fit for almost every high-voltage, wide bandwidth application.
