Pin
Function / Description
Name
3
ONE, / TWO Sweep
High = ONE Sweep (Line or Field)
Low = TWO Sweep (Line or Field)
When going from ONE or TWO to THREE Sweep, input channels 1, 2, and 3 will be
forced on. When going from THREE to ONE or TWO, input channels will be returned to
pre-THREE status if possible.
4
/Remote Sync Enable
Low enables Remote Sync. Level sensitive to enable and edge sensitive to disable. A
Low level turns off CH1 Reference, turns off External Reference, routes TTL Remote
Sync (pin 10) around the sync stripper and directly into the sweep-gating circuitry.
A Low-to-High transition restores previous reference.
If CH1 Reference is selected, Remote Sync will turn it off, and deselecting Remote will
turn it back on.
5
Recall 1
Low-to-High or High-to-Low transition will cause the instrument status to be recalled from
one of four memory locations, determined by the status of pins 5 and 7. The four possible
combinations are:
Memory Pin 5
Pin 7
1
Low
Low
2
Low
High
3
High
Low
4

6
Store
High-to-Low transition will cause the current instrument status to be stored in one of four
possible locations. Refer to the description of Pin 5.
7
Recall 0
Low-to-High or High-to-Low transition will cause the instrument status to be recalled from
one of four memory locations. Refer to the description of Pin 5.
8
/THREE Line or Field
Low =
THREE Sweep (Line or Field).
This pin overrides pins 3, 12, 13, and 14, automatically placing the instrument in a
THREE Line or Field Sweep mode with Channels 1, 2, and 3 turned on.
Low-to-High transition releases the override on pins 3, 12, 13, and 14. The state of those
pins is then determined by the current status of their remote control lines.
9
Ground
10
Input for:
TTL Remote Sync, or
10 V RGB Staircase, or
External Horizontal
50 K input impedance to ground. No pull–up resistor provided for TTL inputs. Polarity of
RGB Staircase and EXTERNAL Horizontal selected by internal jumper setting (A3J5).
11
/Both (CHA & CHB)
Use with CH1, CH2, and /or CH3
Low = Both CHA and CHB On
High-to-Low transition forces the reference to external and turns both CHA and CHB on.
Low-to-High transition has no effect.
