A101 Display

The following table lists signals routed between the A102 DC-DC Converter assembly and the A101 Display assembly. This table shows several things — if the assembly generates or uses the signal or voltage, and if a signal is bidirectional. A description of each signal follows the table.

Signal Name	Pin(s)	A102	A101

SThis assembly is the source of the signal.

• This assembly uses the signal.

— This assembly does not use this signal.

HSYNCELn	Horizontal Synchronization — A low on this line causes a horizontal retrace on the
	A101 Display assembly. Between each HSYNCELn pulse, 560 pixels are sent to the Display
	assembly.
PSENBLn	Power Supply Enable — A low on this line enables the A102 DC-DC Converter assembly’s
	power supply. The power supply generates the driver supply voltages. The driver supply
	voltages are +20 V, +40 V, +215 V, and −175 V.
VCLK	Video Clock — This 20 MHz clock provides the timing reference for HSYNCELn, VID, and
	VSYNCEL. The rising edge of this clock determines setup and hold times.
VID	Video Data — This is the serial data line for the A101 Display assembly. This line transmits
	video data to the Display assembly. The video data is transmitted at the VCLK rate between
	horizontal and vertical retraces (during the time HSYNCELn is high and VSYNCEL is low).
	Only the first 400 lines of data are displayed after a VSYNCEL pulse.
VSYNCEL	Vertical Synchronization — A high on this line causes a vertical retrace on the A101 Display
	assembly.

channel analyzers. The A12 BNC assembly routes the signals connected to the Channel 1 BNC connector and Channel 2 BNC connector to the A1 Input assembly. The A12 BNC assembly also routes the source signal from the A5 Analog assembly to the Source BNC connector. The signal connected to Channel 1 should be between 0.19531 Hz to 102.4 kHz in single channel mode and between 0.097656 Hz to 51.2 kHz in two channel mode. The signal connected to Channel 2 should be between 0.097656 to 51.2 kHz. For both channels, the signal’s amplitude range must be between +27 dBVrms and –51dBVrms for full scale measurements. The source output signal can be random noise, burst random noise, periodic chirp, burst chirp, pink noise, or fixed sine.
