Aeroflex / Tektronix / CDS 53A-128 Communications Card (IEEE-488)

The Aeroflex / Tektronix / CDS 53A-128 Communications Card is a specialized interface module designed for integration into the CDS 53/63 Series System, facilitating communication over the IEEE-488 standard. This card acts as a translator and buffer between the IEEE-488 bus and the host system, enabling the entire chained Card Cage system to be recognized as a single IEEE-488 instrument. It supports various IEEE-488 interface functions, allowing for control of the 53/63 System via a bus compliant with IEEE Standard 488-1978. The card draws power from the 53/63 Series Card Cage’s internal power supply.

### Technical Specifications

* **Interface Standard:** IEEE-488 (GPIB)
* **System Integration:** Designed for use within the Aeroflex / Tektronix / CDS 53/63 Series Card Cage systems.
* **Functionality:** Acts as a communications translator and buffer between the IEEE-488 bus and the 53/63 System.
* **IEEE-488 Bus Data Rate:** Information on specific data transfer rates for the 53A-128 itself is not explicitly detailed, but the general IEEE-488 standard supports data rates up to 1 Mbyte/sec.
* **IEEE-488 Interface Functions:** Compliant with IEEE Standard 488-1978. The card supports functions such as ATN (Attention), SRQ (Service Request), EOI (End or Identify), NDAC (Not Data Accepted), NRFD (Not Ready for Data), DAV (Data Available), REN (Remote Enable), and IFC (Interface Clear).
* **Logic Levels:** TTL compatible.
* **Line Termination:** Each of the 16 bus signal lines is terminated with 3K ohms to Vcc and 6.2K ohms to logic common.
* **Line Drivers/Receivers:** Specific models are not detailed, but the IEEE-488 standard utilizes specific driver and receiver ICs.
* **Data Transfer Modes:** Supports binary and block data transfer.
* **Power Requirements:**
* **Voltage:** 5-volt DC, supplied by the 53/63 Series Card Cage internal power supply.
* **Voltage Range:** 4.75 V dc to 5.25 V dc.
* **Current:** Maximum quiescent current is 0.72 A, with a peak current of 0.75 A. (Note: Some related cards like the 53A-333 and 53A-334 show higher quiescent/peak currents for their respective functions, but for the 53A-128 specifically, 0.72A/0.75A is indicated).
* **Environmental:**
* **Operating Temperature:** 0 °C to +50 °C.
* **Storage Temperature:** -40 °C to +85 °C.
* **Humidity:** Less than 95% RH, non-condensing.
* **Physical:**
* **Dimensions:** (Refer to 53/63 Series Card Cage specifications for overall system dimensions, as the card itself is a component within the cage).
* **Connectors:** Utilizes an IEEE-488 standard 24-pin connector for bus communication. Also connects to the 53/63 Series Card Cage backplane via a front-edge connector.
* **Indicators:**
* **POWER LED:** Indicates system power and can also serve as a diagnostic tool, flashing each time data is sent or received.
* **LISTEN LED:** Illuminates when the 53A-128 card is addressed to listen.
* **System Bus:** The IEEE-488 interface bus typically consists of 16 signal lines and 8 ground lines.
* **Compatibility:**
* Compatible with the Aeroflex / Tektronix / CDS 53/63 Series Card Cage systems.
* Designed to interface with controllers and instruments compliant with IEEE Standard 488-1978.
* Requires specific interface cables such as the 53A-716 Data Cable for connection to the IEEE-488 bus.
