The Tektronix TR502 is a 1.8 GHz tracking generator plug-in for the TM500 system.
The TR502 is intended to work with the 7L13 and 7L14 spectrum analyzer plugins from the 7000 series. It also works with a 7L12.
The TR501 and TR502 are essentially the same instrument with the exception of the output attenuators and logic interface in the TR502, which adds dot marker support for the 7L13 via the TRACK GEN LOGIC connector. A 012-0648-00 cable with 6-pin LEMO Connectors is required for this functionality. The TR503 is similar but has different oscillator and intermediate frequencies (see link).
Freel Telewski was Program Manager for the TR502 projcct. Assisting in electrical designe were Glenn Batenman, Michael McMahon, David Morton, and Phillip Snow. The mechanical design team included Carlos Beeck, Jack McCabe, and Leighton Whitsett.
Key Specifications
| Frequency range | 100 kHz to 1.8 GHz |
|---|---|
| Maximum output level | 0 dBm ±0.5 dB |
| Level range | 0 to –59 dBm |
| Level flatness | ±0.65 dB |
Compatible Counters
The TR502 provides an auxiliary RF output to be used with counters. For accurate measurement of the marker frequency while sweeping, the counter needs to be gated from the TR502 and 7L13. Compatible counters are the DC508 Option 7 or a DP501 prescaler combined with a DC509, DC5009, DC510, or DC5010. For the elaborate interconnects required see the figure below.
