ACB Configurations 1

Introduction 1.1

The ACB (Amplifier Control Board) is a slot-in board used in all Avance systems.There are however various types available depending on the system.

First generation Avance systems 1.2

First generation Avance systems were shipped with the original AQR ACB board(H5483). If your system has an AQX / AQR chassis with boards such as the ASU(Amplitude Setting Unit), the LOT (Local Oscillator Tune) as well as a PTS orSchomandl frequency synthesizer etc. then this is the relevant ACB board for yoursystem. The AQR ACB board is not described in this manual but is described inmanual P/N Z31224.

Second generation Avance systems 1.3

With the more recent AQS system with units such as the FCU3, TCU3, SGU twoACB configurations are possible depending on whether the system amplifiers areinternal or external.

1) The AQS ACB Standard Board ACB-S (H9488) is designed to be usedin Avance systems fitted with internal amplifiers (BLA2BB, BLAX300)mounted within the AQS rack. The board is positioned at the rear of therack as in Figure 1.1. on page 6

2) The AQS ACB Extended Board ACB-X (H9500) is designed to be usedin Avance systems fitted with external amplifiers. The ACB ExtendedBoard is used in conjunction with the AQS PSD Board (H9530). Slot posi-tions of these two boards are shown in Figure 1.2. on page 7.

This manual describes the AQS ACB Standard Board.

Basic Functions 2

Introduction 2.1

In order to reduce costs the ACB standard board (ACB-S) has been designed withlimited on-board processing capability and in many of its functions it acts simplyas a buffer for signals that need to be transmitted to various units. The ACB stan-dard board is connected to

· the internal linear amplifiers via the I2C bus along the AQS backplane

· the (optional) BSMS keyboard via the BSMS CCU

· the HPPR1 via the Console Backpanel and 19 pole periphery connection.

· the HPPR2 via the Console Backpanel and 36 pole periphery connection.

Primary Function 2.2

The primary function of the ACB-S is to display the forward (FORW) and reflected(REFL) linear amplifier power on the BSMS keyboard (when such an option is fit-ted). The information is transmitted from the linear amplifiers to the ACB-S usingthe I2C bus which runs along the AQS backplane. The information is then trans-mitted to the BSMS keyboard via the BSMS CCU.

Note A power display on the graphics monitor is not supported with the ACB-S. Tosee the FORW and REFL display on the monitor a system fitted with the ACB Ex-tended board along with external amplifiers is required.

Secondary Functions 2.3

Secondary functions of the ACB-S are listed below.

· Transmission of the Power down (‘Trans P-Down’) signal from the BSMSkeyboard.

· Transmission of the ‘Chan Select’ signal from the BSMS keyboard

· Transmission of the ‘RGP ADC’ signal to the BSMS keyboard.

· Provision of the power supply voltages +19 V, +9V to the HPPR.

· Transmission of the ‘RGP HPPR’ signal to the HPPR

· Transmission of the ‘Lock PP’ (TGPF0) signal to the HPPR (old nameSPF0)

· Transmission of the ‘Interleave Inc.’ (old name RCP) signal to the HPPR(HPPR2 only).

· Buffer of the 20MHz synchronization clock signal


Basic Functions

As can be seen from the above list the two principal units with which the ACB-Scommunicates externally (as opposed to over the AQS backplane) are the BSMSand the HPPR and these are the subject of the next two chapters.

Cables and Part Numbers 2.4

The table below is a list of the external cabling.

Connections to BSMS Keyboard 3

Introduction 3.1

The ACB-S is linked via the CCU of the BSMS to the BSMS keyboard as in thefigure "ACB-S connections with the BSMS" on page 14

The next section describes the various signals that are transmitted between theACB-S and the BSMS.The pinouts of the various signals are listed in the Appen-dix.

Signal Description 3.2

Display of FORW and REFL power Each RF amplifier has internal ADCs (8 bits resolution) which digitize the rf poweras measured at the amplifier output. Both available amplifier slots are continuous-ly polled by the ACB-S to sample the magnitude of the forward and reflected sig-nal. The data transmission is achieved using the I2C bus which runs along theAQS backplane and effectively connects the ACB-S with the amplifiers.The datatransfer can only take place when the ACB-S is allowed take control of thebus.The SGU is however normally Master of the I2C bus. At the appropriate timethe SGU will send a ‘I2C Bus request ‘signal that allows the ACB-S to becomeMaster of the I2C Bus. Under these conditions a data bit stream containing theFORW and REFL information is received by the ACB-S without interruption. Thiscondition will continue until such time as the SGU becomes Master once again byeffectively removing the ‘I2C Bus request‘.

The digitized information is then passed to the BSMS CCU and then to the BSMSkeyboard where, still in digital form, it is used to light the LED display on theBSMS keyboard.

Note 1:There is no need to individually address the linear amplifiers as all poten-tial amplifier slots will be polled.This is not the case however if external amplifiersare used.

Note 2:Because of the digital nature of the FORW and REFL signals they are notopen to troubleshooting.

Control of the ADC LED on the BSMS keyboardThis LED is controlled by the ‘RGP ADC’ signal which is transmitted along theAQS Backplane after generation by the SGU. The ACB-S simply buffers this sig-nal and it is then transmitted to the BSMS keyboard. The signal is ACTIVE LOWcorresponding to the ADC ‘on’ condition.

Connections to HPPR 4

Introduction 4.1

The ACB-S is linked via the cabinet Backpanel to the HPPR.

The next section describes the various signals that are transmitted between theACB-S and the HPPR.

The pinouts of the various signals are detailed in the Appendix.

Signal description 4.2

+9 V, + 19V DC Power supplies to HPPR.Note that this connection labeled ‘HPPR PSU’ on the front panel was introducedwith ECL002.

The origin of the voltages are the power supply boards AQS PSM1 and PSM2and the ACB-S serves only to transmit these signals to the HPPR.

These voltages are delivered to the HPPR and can most easily be measured atthe 19 pole Preamp Periphery socket or on the HPPR Cover display itself.The pi-nouts for these signals are given in the table below.

Connections to HPPR

RGPHPPR (EP):This signal is generated by the SGU and transmitted to the ACB-S along the AQSbackplane. From here it is connected to the Backpanel and then to the HPPR viathe 19 pole Preamp Periphery socket (HPPR1) or the 36 pole Preamp Peripherysocket (HPPR2). The purpose of the signal is to control the switching of the HPPRbetween transmit and receive mode. The ACB-S acts merely as a buffer and sim-ply passes the signal on to the HPPR.

Note: This signal was formerly referred to as EP.

LOCK PP (TGPF0)This is the gating pulse for the lock preamplifier. The signal is pulsed at the fre-quency of 6.6kHz (regardless of whether a 2H or a 19F lock is used). The signaloriginates on the BSMS LTX board and is transmitted to the ACB-S via the exter-nal sma type cable which is connected to the ACB-S front panel.

Note: On earlier Avance instruments this signal was known as SPF0.

INTERLEAVE INC (RCP) This signal has not yet been implemented. The signal could be used for fastswitching between the selected preamps during a pulse program where theRS232 control would be too slow. This would allow the selected OBS HPPR mod-ule to be switched during an acquisition. This feature may be implement in the fu-ture HPPR2 model. The signal is generated by the SGU and transmitted to theACB-S. From here it is connected to the Backpanel and then to the HPPR2 via the36 pole Preamp Periphery socket (HPPR2)

Note: The signal was formerly referred to as RCP.

20MHz clock signalThis signal is used to ensure FCU and SGU synchronization. The ACB-S actsmerely as a buffer. The signal is transmitted along the AQS backplane.


Additional Information 5

Switching on / Initialization Routine 5.1

The ACB-S requires no initialization due to the simplicity of the on board micropro-cessors. Once the board has been switched on it is ready to function.

Firmware Update 5.2

There is no download possibility as firmware updates will not be required. Thefirmware will not be updated with new XWIN-NMR versions.

Power Supply 5.3

The board requires 5V(Vcc) and +12V (SBS) power supply. Both of these voltag-es are taken from the corresponding PSM Modules over the backplane.

ECL Level 5.4

Current level (March 2000) is ECL002. This level was the first to be shipped tocustomers.With the introduction of ECL002 (2/12/99) an additional power supplyconnector for the HPPR2 was added to the front panel

Board Replacement. 5.5

This requires no special precautions. Simply power off the console and replace.
