90PGA Slot Card

Section 1 Dual Channel Programmable
Front Panel Operation Amplifier Card

1.1 - Start Up

All 90PGA slot cards should be inserted into the 90IP chassis and controller while the power switch (rear
panel) is in the OFF position (O). Once all slot cards have been inserted, the power switch can be moved
to the ON position (I). Upon power-up, a micro-controller on each 90PGA slot card sends its configuration
to the 90IP controller which can then be shown on the display. This is Frequency Devices’ SMART SLOT
Technology. See 90IP Operations Manual for chassis and controller operating instructions.

See Figure 1 - Front Panel below

1.2 - 90 PGA Operation Instructions

1. Upon power up, a cursor appears under the default function value or mode. (Note the cursor is always
initially displayed on the LSB of any numerical value.)

2. Turning the FUNCTION knob scrolls the cursor through the various function selections.

3. To make a change, press the ENTER button and the addressed character will blink.

4. Turning the SELECT knob will alter the value of the desired character or mode.

5. Pressing the ENTER button again, loads the selected value or configuration into the slot card and
controller memory and the blinking stops.

6. After a
by using the FUNCTION and SELECT knobs.

7. Once the channel is programmed or configured, it may also be saved in one of the nine configuration
locations. Since it is the most recent configuration setting, it automatically becomes the new power-up
default for that channel.

8. User must press ENTER button to select and activate all configurations. This is done on a per
channel basis.

90PGA Slot Card

Section 1 Dual Channel Programmable
Front Panel Operation Amplifier Card

90PGA slot cards can be addressed from either the 90IP hard front panel or by using a computer controlled
soft front panel via the GPIB or RS232 communication port on the rear of the 90IP chassis. See page 7 for
Remote Operation instructions.

Operating functions with available ranges or acceptable modes are listed below in the command structure
listing.

1.3 - Front Panel Command Structure

1. ADD – Identifies current chassis location within

the GPIB communication system structure. For
individual chassis, the default address reads “01”.

ADD

2. SLOT – Each 90IP chassis can be populated

with one (1) to four (4) slot cards. This command
allows the user to independently select and
configure each slot card.

SLOT

3. CHAN – Each 90PGA slot card contains two

(2) channels of programmable gain. The CHAN
command allows the user to independently select
and configure each 90PGA channel.

CHAN

4. MODE – Determines coupling requirements

and single-ended or differential types for the input
signal.

MODE
DC–DC

Note: Output is always single ended.

5. GAIN – Gain selection is performed by setting

each individual digit.

GAIN

6. OFFSET – Offset is preset for every card at

room temperature. Because of thermal drift and
high gain settings, fine-tuning of DC offset is
sometimes required. Offset adjustment is
performed sequentially.

7. CONFIG – Up to 9 configurations can be saved
on each 90PGA channel. Slot card configuration
in use at time of power-OFF will be saved to the
next power ON cycle. Enter bolds the d in saved.

CONFIG
S - Saved

8. REMOTE – Displays Local reset screen when

external computer has control of the instrument in
remote operation. On power-up, Instrument
defaults to local mode. During a remote session,
press ENTR to return to local mode. Remote
mode can only be initiated by an external
computer.

REMOTE

LCL - Local ENTR – RS232 or GPIB

9. LED’s – Each 90PGA contains one clipping

section per channel for gain output. This output
is the input into the clipping circuitry. The input
passes through a comparator and when peak
voltage is greater than +10.5 V or less than –

10.5V, CLIPPING occurs and the red LED’s will
light.

Note:

Outputs of the slot cards are always DC-Coupled.

2.1 –Directory Descriptions CDFC-01

The CDFC-01, 90IP Function Cards Installation Disk contains documents in Word and PDF formats that
include the 90PGA data sheet and this User Manual. Also included are set-up directories for each function
card user interface, the function cards driver, and the instrument control software. These set-up directories
are:

1 – 90FC Instrument Driver (For Custom Applications)

This directory will install the code and the files needed to develop custom applications using the 90PGA
or any other function cards available to date.

2 - 90IP Instrument Control
This directory will install the LAUNCH SLOT CARD CONTROL software and install the 90IP

INSTRUMENT SLOT CARD CONTROLLER CONFIGURATION software.
3 - 90PGA User Interface (For Custom GUI Development)

This directory installs the code and the files used in developing the 90PGA GUI.
Note: Additional directories will depend on function cards available to date. These directories

install the code and the files used in developing the function card GUI’s for custom
development.

Follow the process instructions to install any utility into a desired local directory. Each directory offers
installation software for function card configuration tools such as the 90PGA. Note that clicking on setup

after installation uninstalls the software.

CDFC-01 software uses the 90IP to start the configuration process through the communication interface
(either GPIB or RS232). The 90PGA Slot Card Controller (SCC) is used to read and set the configuration
of valid 90PGA cards.

The 90PGA, SCC performs the following functions:

• Provides communication with the controller interface,

• Provides slot card access,

• Provides slot card set-up, and

• Discontinues slot card operation (Stopping).

It is designed to allow the user to select the channel and gain parameters through the software front panel.
By setting the values with the soft front panel, the software automatically configures the 90PGA card
without the need to use the 90IP hard front panel instrument controls. For this to occur, the SCC monitors
event changes in each soft panel control and runs various routines accordingly. Multiple slot cards may be
arranged to work simultaneously without affecting each other.
