The Tektronix RG501 is a ramp generator plug-in for the TM500 system.
It produces a linear ramp signal adjustable up to 10 V amplitude, positive or negative, with a duration from 10 μs to 10 s (equivalent to 1 μs/Div to 1 s/Div on a typical oscilloscope's X scale). Additionally, the RG501 provides a 3 V (TTL compatible) gate signal (high while ramp running).
The ramp can be triggered from an external input, an internal trigger signal (via the backplane), the line frequency, or can be free-running (Auto Trig mode).
A typical application of the RG501 is to sweep a voltage-controlled function generator's frequency, e.g. when used with with the FG501.
Key Specifications
| Ramp duration | Fixed, 10 μs to 1 s in decade steps, variable multiplier ×1 to (min.) ×10 (i.e. max. 10 s) |
|---|---|
| Amplitude | variable from ~50 mV to 10 V, selectable polarity |
| Trigger | Sensitivity 200 mVp-p, Level ±1 V, input impedance 10 kΩ |
| Gate output | 3 V, 160 Ω source impedance |

| 28A | Ramp output (common on 27A) |
| 25A | Gate output (common on 26A) |
| 24B | Internal trigger input (common on 25B) |

Internals
The RG501 uses Tek custom ICs 155-0056-00 (sweep control) and 155-0042-03 (Miller integrator).
Service Notes
If Line Trigger is OK but the power supplies load down in other trigger modes, suspect Q15 is installed incorrectly because of different case styles.
