Controls & Indicators
The front-panel controls/indicators for the ESM 500 A-F include:
1. SSB: Allows selection of operating modes AO, ISB, AT, LSB, USB, ISB with a tuning step of 100 Hz/step.
2. DISPLAY kHz: Switches frequency indication from MHz to kHz and reduces tuning step to 10 Hz/step.
3. HF 40 dB: Pushbutton for switching in 40 dB of RF attenuation for MGC and SSB operation, and for RF panorama display with EZP. In AM and FM operation with AGC, the 40-dB attenuation is automatically switched in for large input levels, indicated by the +40-dB LED on the SIGNAL level meter.
4. AGC: Automatic gain control, with 40 dB of RF attenuation automatically cut in for input signal levels exceeding 75 dByV.
5. MGC: Manual gain control in the range of 80 dByV with 40, with control voltage indicated.
6. ZF-IF-PANORAMA: IF display in the range +100 kHz from the received centre frequency.
7. SIGNAL: Displays RF input level in dByV. +40-dB LED indicates additional 40 dB to be added to the indicated value. Squelch threshold is indicated if the signal is too small.
8. ABLAGE TUN. ERROR: Tuning error indication shows relative offset, sensitivity adjusted to IF bandwidth.
9. AFC: LED lights when automatic frequency control is active, with a capture range of one-half the IF bandwidth, functioning with signals > 1 µV.
10. MHz: Main panel meter with status indication, showing receiver frequency with IF display.
11. MARKEN-FREQ.: Marker frequency with RF display using the EZP.
12. Transfer of instrument status to selected memory location.
13. Memory location or address of a hand-off receiver, with blinking indication if frequency does not match stored value.
14. Transfer of frequency indicated to the main display.
15. Transfer of frequency from auxiliary display to memory.
